fix!: removed names point to their replacement; quieter output for coding agents by dgedon · Pull Request #2164 · sbi-dev/sbi

dgedon · 2026-11-11T12:46:09Z

Summary

Coding agents write sbi code from memory of older APIs, read the output of their
scripts as captured text with limited space, and act on messages literally. This PR
fixes the places where sbi trips them up, and does the removals that #1962
scheduled for v0.28.0.

 >>> from sbi.inference import SNPE
-FutureWarning: `sbi.inference.SNPE` is deprecated since sbi v0.27.0 …   (import works)
+ImportError: `SNPE` was removed from sbi. Use `from sbi.inference import NPE` instead.

 $ TQDM_DISABLE=1 python npe_tutorial.py 2>&1
-Training neural network. Epochs trained: 1 … 62, sampling bars …        (3,246 chars)
+Neural network successfully converged after 62 epochs.
+RESULT posterior predictive mean: tensor([0.8124, 0.6143, 0.4069])     (122 chars)

Removed names fail with the replacement: the v0.27 aliases, infer(method="snpe"),
prepare_for_sbi, sbi.utils.posterior_nn, the vector field builders such as
build_flow_matching_estimator, and old module paths such as sbi.inference.snpe.
The names come from one list in sbi/utils/removed_names.py.
sample_with in VectorFieldPosterior.sample() is removed, as scheduled in deprecation: warn on the legacy aliases, remove in 0.28 #1962.
It is set at construction, e.g. build_posterior(sample_with="ode").
NPE, NLE and NRE are what the errors suggest, and they are now in
sbi.inference.__all__, together with infer.
TQDM_DISABLE=1 turns off all progress output, including the bars of the Pyro
and PyMC samplers. sbi passed disable= to every bar, which overrode the variable.
Progress lines are now flushed and end with a newline.
Module loggers instead of the root logger, so the user's
logging.basicConfig() keeps working.
Low-acceptance warning: it no longer fires after sampling has finished
("remaining -48 samples").
Shape error: it names theta or x instead of always blaming x_o.
Docs entry points: llms.txt links point to the docs version being built, and it
mentions TQDM_DISABLE=1. The README points to it.

Evidence

from sbi.inference.base import infer: before, No module named 'sbi.inference.base';
now … Use `from sbi.inference import infer` instead.
An sbi warning, then logging.basicConfig(level=logging.INFO): before, the user's INFO
messages never appeared; now they do.
Captured output with TQDM_DISABLE=1 (tokens, o200k_base): NPE tutorial 856 → 35;
simulate_for_sbi + NLE + MCMC 4,630 → 34. Pyro NUTS and PyMC HMC: before, about 1 KB
of bars on stderr (Pyro) and 0.7 KB on stdout (PyMC); now none. Without the variable,
output keeps its size. A terminal shows the same as before, except that the progress
line now ends: the last epoch count stays visible, and the "converged" message starts
on its own line.
Each new test fails on main and passes here. The fast suite and CI pass.

For the 0.28.0 release notes

The old trainer names (SNPE, SNPE_C, APT, SNLE, SNRE, SRE, AALR, CNRE,
ABC, SMC and the other aliases deprecated in v0.27.0) are removed. Use NPE,
NLE, NRE, NPE_A, NRE_A, NRE_C, MCABC or SMCABC. Importing an old name
raises an ImportError that names its replacement.
infer() no longer accepts the old method names such as method="snpe". Use
method="npe", "nle" or "nre".
build_flow_matching_estimator, build_score_matching_estimator and
build_vector_field_estimator are removed. Use an estimator config's .build(), e.g.
FlowMatchingConfig().build(theta, x) or VEScoreConfig().build(theta, x) from
sbi.neural_nets.
VectorFieldPosterior.sample() no longer takes sample_with. Set it at construction,
e.g. build_posterior(sample_with="ode").
Old module paths (sbi.inference.base, sbi.inference.snpe, .snle, .snre,
sbi.utils.posterior_ensemble) and the older removed names prepare_for_sbi and
sbi.utils.posterior_nn/likelihood_nn/classifier_nn now raise an ImportError
that names the new import.
TQDM_DISABLE=1 turns off all progress output, including the "Epochs trained" counter
and the Pyro and PyMC sampler bars.
sbi logs its warnings under sbi.* loggers instead of the root logger. Without a
logging setup, they print without the WARNING:root: prefix.

Merge Danger

Door: one-way for users: code that uses the removed aliases, old infer method
strings, the vector field builders or sample_with in VectorFieldPosterior.sample()
stops working, as announced for v0.28.0. Two-way in code: a revert restores the
warnings.

Blast Radius: user code.

hasattr() with a removed name, e.g. hasattr(sbi.inference, "SNPE"), raises instead
of returning True.
Without a logging setup, sbi's warnings print without WARNING:root:.
A new ruff rule (TID251) bans direct tqdm imports. feat: parallel simulation with simulate_from_theta and parallelize_simulator #1738 adds some; importing from
sbi.utils.pbar fixes it.
Small merge conflicts with fix: keep Standardize mean and std only as buffers, so .to() moves them #2155, feat: parallel simulation with simulate_from_theta and parallelize_simulator #1738 and refactor: import configs only from sbi.neural_nets, remove build_zuko_cnf, merge z-score embedding helpers #2162 (sbi/neural_nets/net_builders/__init__.py).

Does this close any issues?

It completes the removal scheduled in #1962. Related: #1821, #1868.

Anything else we should know?

build_vector_field_estimator also built score estimators; its error points to
FlowMatchingConfig, its default.
The builders were defined in sbi.neural_nets.net_builders.vector_field_nets, and
importing them from that module still gives a bare "cannot import name". Happy to add a
__getattr__ there too.
Follow-up for refactor: import configs only from sbi.neural_nets, remove build_zuko_cnf, merge z-score embedding helpers #2162: it removes build_zuko_cnf, so once this PR is merged it should
add that name to REMOVED_NAMES.

Checklist

I have read the contributing guide.
uv run pytest -n auto -m "not slow and not gpu" passes.

uv run pyright sbi passes.
I added or updated tests for the changed behavior.
I used Google-style docstrings for new or changed public functions.
New tests take about 10 s in total; none is slow.

The legacy aliases (SNPE, SNLE, SNRE, APT, ABC, SMC, ...) and the matching `infer(method=...)` strings warned since v0.27.0 and are removed for v0.28.0, as scheduled in sbi-dev#1962. Names and modules removed earlier (prepare_for_sbi, sbi.utils.posterior_nn, sbi.inference.base, sbi.inference.snpe, ...) failed with a bare "cannot import name" or "No module named". All of them now raise an ImportError (a ValueError in `infer`) that names the replacement, from one list in `sbi/utils/removed_names.py`. Placeholder files at the removed module paths raise the same error. This replaces the four alias tables and their copied `__getattr__` functions. The `__getattr__` hooks are hidden from type checkers: pyright accepts any name from a module that defines `__getattr__`, so it now flags removed and unknown names again. BREAKING CHANGE: the legacy aliases and `infer` method strings no longer work. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

sbi passes `disable=` to every progress bar, and tqdm lets an explicit `disable=` override the `TQDM_DISABLE` environment variable, so the variable silenced only some bars. The epoch and MAP counters are plain prints and never listened to it. All bars now use `tqdm`/`trange` from `sbi.utils.pbar`, a `tqdm.auto.tqdm` subclass that the variable turns off, and the five counters use `print_progress()`, which checks the same variable. A ruff rule (TID251) keeps new code from importing tqdm directly. The "converged" message now ends with a newline, so the next output starts on its own line. In captured output, `\r` does not overwrite, so a five-minute MCMC run sent about 230k characters of progress to tools that read the output, e.g. coding agents. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Twelve warnings went through `logging.warning()`, which configures the root logger on first use. After the first sbi warning, e.g. "Found 10 NaN simulations", the user's own `logging.basicConfig()` silently did nothing. The four modules now log through `logging.getLogger(__name__)`, as other sbi modules already do. The messages still reach the root logger's handlers, and users can filter them by the `sbi.` logger names. Without any logging setup they now print without the "WARNING:root:" prefix. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Both rejection samplers checked the acceptance rate after every batch, also after the last one. When that batch finished sampling, the warning still fired and advised interrupting or switching methods, about "the remaining -48 samples". Users, and coding agents that act on warnings literally, then switched methods for a run that had already succeeded. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The shape check runs on both theta and x, but its message always blamed `x_o`, so a wrong theta shape sent users, and agents that fix what the message names, to the observation. Also fix "the use the simple interface" in `infer()`. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The epoch and MAP counters overwrite one line and leave it open. Only a converged neural trainer ended it, with its "converged" message. Training that stopped at `max_num_epochs`, the marginal trainer, the restriction estimator, sensitivity analysis and MAP optimization left it open, so the next output continued it, e.g. "Epochs trained: 31RESULT: done". Tools that read the output line by line, e.g. coding agents, then saw the result inside the progress line. `end_progress_line()` ends the line after each loop, unless progress output is off. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

`infer` was importable but missing from `__all__`, so `help(sbi.inference)` and `from sbi.inference import *` left out the one-line interface the docs recommend. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

`llms.txt`, the docs index for coding agents, linked every page to `/en/latest/`, also when served from `/en/stable/`. Agents using the installed release then read docs for unreleased API. A post-build step now rewrites the links in the built copy to Read the Docs' URL for the version being built. Local builds are unchanged. The README, which is also the PyPI page, now points agents to the index. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

`sbi.__doc__` was None. `help(sbi)` and `sbi/__init__.py` are often the first things a coding agent reads in an installed package, and the repo's AGENTS.md is not in the wheel. The docstring shows a minimal NPE workflow and links the release docs and llms.txt. A test runs its imports, so a renamed name fails CI instead of leaving the docstring stale.

Walkthrough

The changes add replacement-directed errors for removed APIs, centralize progress-bar and printed progress controls, and update documentation links. They also route warnings through module loggers, adjust a rejection-sampling warning condition, and clarify shape-mismatch messages.

Changes: Documentation index

Layer / File(s)	Summary
Canonical documentation links `README.md`, `docs/conf.py`	The README directs coding-agent users to the stable documentation index. The Sphinx build updates `llms.txt` links to the configured canonical URL when its conditions are met.

Removed API handling

Layer / File(s)	Summary
Removed-name mappings and handlers `sbi/utils/removed_names.py`	A new utility maps renamed inference methods, removed public names, and removed modules to replacements. Its handlers raise replacement-directed errors for known removed identifiers.
Inference API and module handling `sbi/inference/`, `sbi/inference/trainers/`, `sbi/utils/__init__.py`, `sbi/neural_nets/net_builders/__init__.py`	Inference exports and trainer packages use shared removed-name handling. Removed modules raise replacement-directed import errors, and `infer` rejects renamed method strings.
Posterior API changes and validation `sbi/inference/posteriors/vector_field_posterior.py`, `tests/base_test.py`	`VectorFieldPosterior.sample()` no longer accepts a per-call sampling method. Tests check canonical exports, replacement errors, renamed methods, and removed modules.

Centralized progress output

Layer / File(s)	Summary
Progress controls and usage guidance `sbi/utils/pbar.py`, `pyproject.toml`, `docs/llms.txt`	The shared progress module adds environment-based disabling for bars and printed progress. Ruff bans direct tqdm imports, and the documentation describes how to disable progress output.
Progress utility adoption `sbi/analysis/sensitivity_analysis.py`, `sbi/diagnostics/`, `sbi/inference/posteriors/`, `sbi/samplers/`, `sbi/simulators/`, `sbi/inference/trainers/`, `sbi/utils/`	Analysis, diagnostics, posterior, sampler, simulator, trainer, and utility code uses shared progress utilities. Pyro and PyMC progress settings also account for global disabling.
Progress and output tests `tests/pbar_test.py`, `tests/base_test.py`	Tests cover progress output with `TQDM_DISABLE` set and unset, Pyro progress-bar disabling, stdout flushing, and training output line endings.

Warnings and input messages

Layer / File(s)	Summary
Module-scoped warning logging `sbi/analysis/sensitivity_analysis.py`, `sbi/utils/plotting_helpers.py`, `sbi/utils/sbiutils.py`, `tests/sbiutils_test.py`	Analysis and utility warnings use module loggers instead of root logging calls. A test checks the logger name for a clamp warning.
Rejection-sampling warnings `sbi/samplers/rejection/rejection.py`, `tests/rejection_sampling_test.py`	Rejection-sampling warnings use a module logger. Low-acceptance warnings are emitted only while samples remain, and tests cover two requested sample counts.
Shape-mismatch messages `sbi/neural_nets/estimators/shape_handling.py`	Shape-mismatch errors identify theta or x as the input.

Full details: Title check

Explanation

The title names the main change: removed deprecated names now fail with a replacement-directed ImportError, plus quieter output for coding agents. Both parts match the changeset (removed_names.py, TQDM_DISABLE handling, llms.txt, pbar changes). The title is 80 characters, which is slightly long, but the content is accurate and specific. The title uses the fix! conventional-commit marker, which signals a breaking change and fits the removals.

Full details: Description check

Explanation

The description follows the template sections: What does this PR do (Summary), Does this close any issues (linked to #1962, #1821, #1868), Anything else we should know (Merge Danger, edge cases, follow-ups), and the checklist. It adds Evidence and release notes beyond the template, which is acceptable. The checklist is filled in. The description does not link a fixed issue with a 'Fixes #' line, so it says 'completes the removal scheduled in #1962' instead. The AI-assistance disclosure HTML comment is still present as a TODO-style note, and the author states the tool used in the final line. Overall the description is complete and specific.

On a terminal, Python flushes stdout when a write contains a newline or "\r". `print_progress()` writes the leading "\r" first and the message after it, so each message waited in the buffer for the next one: the epoch and MAP counters showed nothing during the first epoch and then lagged one update behind. The restriction estimator printed with `end="\r"` before it used `print_progress()`, and did not lag. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The errors for removed names pointed to `NPE_C`, `NLE_A` and `NRE_B`, while the README, the tutorials and the package docstring use `NPE`, `NLE` and `NRE`. Each removed name now points to the shortest current name of the same class: `SNPE`, `SNPE_C` and `APT` to `NPE`, `SNLE`, `SNLE_A` and `SNL` to `NLE`, and `SNRE`, `SNRE_B` and `SRE` to `NRE`. Names of other variants keep them, e.g. `SNPE_A` points to `NPE_A`. `infer(method="snpe")` now suggests `"npe"`. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

`NPE`, `NLE` and `NRE` are the names the docs teach, and the removal errors now point to them, but `__all__` left them out. `help(sbi.inference)` and `from sbi.inference import *` now include them. This settles the naming question that sbi-dev#1962 left open. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

@dgedon thanks, errors that name the replacement are a really useful change. Some points below, mostly small.

On your two open questions: please drop the package docstring. It repeats the README, and in PR #1868 we agreed that agents learn more from the code. And yes, please mention TQDM_DISABLE=1 in llms.txt: that is where agents look, and the output savings depend on it.

Two things for the v0.28 removal that the diff does not touch yet:

PR #1962 also scheduled passing sample_with to VectorFieldPosterior.sample() for removal in v0.28. It still warns "will be removed in v0.28.0", so let's remove it here as well.
Please add a short "For the release notes" section to the PR body, as in PR #1962, that says what users have to change.

With TQDM_DISABLE=1, the Pyro samplers still print warmup and sampling bars: Pyro passes disable= to its own tqdm bar, the override this PR fixes for our bars. PyMC draws its own bar too. Please combine the variable with the flag we pass to both backends, with a test for one.

Done in f020ba2: both flags now combine show_progress_bars with progress_disabled(). test_tqdm_disable_turns_off_pyro_bars replaces Pyro's MCMC with a stand-in and checks the flag it receives. A test that reads the output would pass even without the fix in CI, because Pyro turns its bars off when CI or PYTEST_XDIST_WORKER is set. In real runs with TQDM_DISABLE=1, Pyro now prints no bars to stderr, and PyMC's stdout went from 680 bytes to 0.

build_flow_matching_estimator and build_score_matching_estimator were deprecated in v0.27 as well (PR #1962), and build_vector_field_estimator is gone too. Importing any of them still fails with a bare "cannot import name". Please add all three here, pointing to an estimator config's .build() (e.g. FlowMatchingConfig or VEScoreConfig from sbi.neural_nets), and give sbi.neural_nets.net_builders the same __getattr__.

Done in cd0da4c. The three names point to from sbi.neural_nets import FlowMatchingConfig; FlowMatchingConfig().build(theta, x), with VEScoreConfig for score matching, and the test now runs each replacement. sbi.neural_nets.net_builders has the __getattr__. Importing from sbi.neural_nets.net_builders.vector_field_nets, where the builders were defined, still gives the bare error; I can add a hook there too if you like. #2162 edits the same __init__.py, so whichever PR merges second has a small conflict.

Because of the leading "\r", captured output with TQDM_DISABLE=1 starts with a carriage return and a space. End the progress line first, as the else branch does, then print plainly.

Done in 6b1043f: the progress line is ended first, then the message is printed plainly. With TQDM_DISABLE=1, captured output is now exactly Neural network successfully converged after N epochs.\n, which test_converged_message_is_plain_when_captured checks.

Optional: callers must know whether a progress line is open, hence the guards around end_progress_line(). If pbar remembered that print_progress() opened a line, end_progress_line() could do nothing otherwise, and those guards could go.

Done in 6b1043f: print_progress() records that it opened a line, and end_progress_line() does nothing otherwise. The four guards are gone.

The new test covers this guard only in accept_reject_sample. Please add the same check for rejection_sample.

Done in 41d431f: the test now runs both samplers. For rejection_sample the proposal is also the target and m=200, so 0.5 % of samples are accepted. Both 10-sample cases fail on main.

It repeated the README, and agents learn more from the code (sbi-dev#1868). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Pyro passes `disable=` to its own tqdm bars, which overrides the variable, and PyMC draws its bar with rich, which ignores it. Combine the variable with the flag sbi passes to both backends. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

It started with the `\r` that overwrites the epoch counter, so captured output with TQDM_DISABLE=1 began with a carriage return and a space. `end_progress_line()` now ends the line only if `print_progress()` left one open, so callers no longer guard it.

`build_flow_matching_estimator` and `build_score_matching_estimator` were deprecated in v0.27 (sbi-dev#1962), and `build_vector_field_estimator` is gone as well. Importing them from `sbi.neural_nets.net_builders` failed with a bare "cannot import name"; the error now names an estimator config and its `.build()`.

dgedon · 2026-11-13T10:40:32Z

Thanks a lot for the review, Jan! All points are addressed:

Package docstring dropped (dca8c21).
llms.txt mentions TQDM_DISABLE=1 (3aa309c).
sample_with is removed from VectorFieldPosterior.sample() (6622a39). Passing it now raises Python's TypeError for an unexpected keyword argument; the release notes give the fix.
The description has a "For the 0.28.0 release notes" section.

The inline comments each have a reply with the commit that addresses them. CI and CodeRabbit pass on the new head.

The message for SNPE read as if sequential NPE itself had been removed. For the old sequential names and their module paths, it now says that NPE, NLE and NRE run multi-round inference and links the how-to guide.

The open line leaked into later tests in the same process: test_converged_message_is_plain_when_captured failed with a leading newline when it ran after the flush test.

janfb · 2026-11-13T11:54:48Z

@dgedon thanks, this covers everything. One nitpick I just fixed myself here to save us another review turn: the ImportError message sounded like we actually removed the SNPE method itself, now we say we just removed the name and point to the how-to-guide.
and two other small points.

The flush test ends its progress line, which otherwise leaked into later tests in the same process.

fix: export infer from sbi.inference

`infer` was importable but missing from `__all__`, so `help(sbi.inference)` and `from sbi.inference import *` left out the one-line interface the docs recommend. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
