Quickstart Examples Not Working

[avilay]

The following commands result in an AttributeError: module 'reagent.gym.tests.test_gym' has no attribute 'run_test’ because the module test_gym does not exist.

export CONFIG=reagent/gym/tests/configs/cartpole/discrete_dqn_cartpole_online.yaml
./reagent/workflow/cli.py run reagent.gym.tests.test_gym.run_test $CONFIG

See full stacktrace here.

Even when I try to run one of the existing modules like run_test_online_episode I get a KeyError: 'state_features'...float_features=batch[InputColumn.STATE_FEATURES]

Here is the full command:

./reagent/workflow/cli.py run reagent.gym.tests.test_gym.run_test_online_episode $CONFIG

See full stacktrace here

On further trying the batch RL example the first command running the offline_gym module works fine. However, the second command running the timeline_operator errors out with java.lang.StringIndexOutOfBoundsException: begin 0, end 3, length 2. Here are the full commands that I ran:

export CONFIG=reagent/workflow/sample_configs/discrete_dqn_cartpole_offline.yaml
./reagent/workflow/cli.py run reagent.workflow.gym_batch_rl.offline_gym $CONFIG
./reagent/workflow/cli.py run reagent.workflow.gym_batch_rl.timeline_operator $CONFIG

Here are my environment details:

• Hardware: Apple M1
• OS: Big Sur 11.2
• Anaconda Python 3.7

• JRE Details

  • openjdk 16 2021-03-16
  • OpenJDK Runtime Environment Zulu16.28+11-CA (build 16+36)
  • OpenJDK 64-Bit Server VM Zulu16.28+11-CA (build 16+36, mixed mode)
• ReAgent master branch cloned on 4/23.
• I had to install a later version of OpenAI gym (0.18.0) because of compatibility issues with M1.

I was having the same issue, and after looking through test_gym.py code change history, I believe run_test was renamed run_test_replay_buffer. I tried:

./reagent/workflow/cli.py run reagent.gym.tests.test_gym.run_test_replay_buffer $CONFIG

and got it to work.

For your first problem, @oshrinm's solution above worked for me. Similar solution to the 2nd problem where you had:

./reagent/workflow/cli.py run reagent.workflow.gym_batch_rl.offline_gym $CONFIG

Replace that with:

./reagent/workflow/cli.py run reagent.workflow.gym_batch_rl.offline_gym_random $CONFIG

Looks like this was also renamed - I think the documentation just needs to be updated.
