Impossible to replay BEHAVIOR VR demo, and more

There are basically two methods I tried to replay (as of June 14).

Method 1

BEHAVIOR: master branch. iGibson: master branch. BDDL: master branch. Dataset: version 2.0.6.

Command: python -m igibson.examples.learning.demo_replaying_examples Results: I can see the demo, but the the motion of the robot is different from ground truth environment. I believe I faced a similar (or even worse) issue as https://github.com/StanfordVL/iGibson/issues/161#issuecomment-1022341060. I know it may because I am not running demos on a Windows machine, but it also shows the below messages and I don't know what's going on. I simply cannot find the vr-demo-collection branch at all. Also, the version 2.0.6 is suspicious, I don't know which version is correct for reproducing the demo.

Creating environment and resetting it

Method 2

BEHAVIOR: master branch. iGibson: behavior-replay branch. BDDL: master branch / behavior-refactored-verified-problems. Dataset: version 2.0.6.

Command: python -m igibson.examples.behavior.behavior_demo_replay Results: Error, no module named 'bddl.activity_base'. / Error, no module named 'igibson.task'

Other issues

Missing action primitive baselines. Behavior cloning baseline training okay, testing failed. BDDL branch is confusing, document not finished, cannot run the code follow the default readme.md (I guess it's an older version?). BDDL behavior-refactored branch pytest failed.

Summary

In short, impossible to replay at all. Can anyone write a detailed instructions on that? If you want the benchmark get attention, at least people can reproduce the basic things easily, right? Many instructions are not up-to-date and show many inconsistencies. Can anyone tells me which one is the correct one to reproduce the vr demo? This https://github.com/StanfordVL/behavior/blob/main/docs/vr_demos.md does not work.
