Issue/Exception with retrieving output tensors

The test class RunModelsTest has two test methods:

🟢 testRunTensorFlowModel: original method from JRedisAI test suite - PASS
🔴 testRunTorchScriptModel: the method in question - FAIL

Using RedisAI docker image edge

docker run -p 6379:6379 --name redisai redislabs/redisai:edge-cpu

Run with

./mvnw clean verify

The method loads a TorchScript pre-trained model that was created using https://github.com/redis-developer/redisai-iris

@bsbodden Did you try the test on redisai:edge-cpu-bionic image?

[bsbodden]

-cpu-bionic

Just did. Same result.
