Error when running bin/examine.py without the pre-trained model

Whenever I try to run the environments such as base or hide_and_seek through the bin/examine.py hide_and_seek or base commands I receive this error:

Inferred:
	names: hide_and_seek.py
	arguments: {}


Traceback (most recent call last):

I’m not sure how to fix it and running the environments with the pre-trained models works perfectly fine.

I had the same problem and fixed it with pull request #22 .

I had the same error. I fixed it by running it like this:

python bin/examine.py examples/blueprint.jsonnet examples/blueprint.npz

It has something to do with the imports I think. So just be outside the “bin” folder, and run this command.
