Bug description

Seeing this error when running quickstart scripts: KeyError: 'Ingredient for named config "environment.fast" not found'

Steps to reproduce

1. conda create -n imitation1 python=3.8

2. conda activate imitation1

3. git clone -b v0.3.1 https://github.com/HumanCompatibleAI/imitation.git

4. cd imitation

5. pip install -e ".[dev]" (which results in a very long stack trace ending in:

   File "/Users/kierad/miniconda3/envs/imitation1/lib/python3.8/site-packages/setuptools/_distutils/unixccompiler.py", line 187, in _compile
         raise CompileError(msg)
     distutils.errors.CompileError: command '/usr/bin/gcc' failed with exit code 1
   
     [end of output]
   
   note: This error originates from a subprocess, and is likely not a problem with pip.
   ERROR: Failed building wheel for grpcio
   Running setup.py clean for grpcio
   Successfully built imitation
   Failed to build grpcio
   ERROR: Could not build wheels for grpcio, which is required to install pyproject.toml-based projects

   but it does say that imitation was built successfully.)

6. python -m imitation.scripts.train_rl with pendulum environment.fast policy_evaluation.fast rl.fast fast logging.log_dir=quickstart/rl/ which produces the error:

   Exception originated from within Sacred.
   Traceback (most recent calls):

Hi @kierad. Thanks for reporting this bug. It occurs in the v0.3.1 version which is from July last year. The current master does not have this issue so I recommend trying that one. We will hopefully have a new release soon with the bugfix (see the milestone here)!
