You should call train, and other CLI tools, as modules, i.e. "PYTHONPATH=$SOCKEYE python3 -m sockeye.train ". Calling directly train.py generates the import error you are seeing.

It may have been the case that direct invocation worked before, but it was not explicitly supported.

That fixed it, thanks.
