An error occurred while running eval.py

[zqy-an]

Hello! Your work looks great!

When I run the eval.py file with reference to readme.md, I get an error:

"/home/zqy/code/robotics/RVT/rvt/libs/YARR/yarr/utils/rollout_generator.py", line 40, in generator
    obs = env.reset_to_demo(eval_demo_seed)
  File "/home/zqy/code/robotics/peract/helpers/custom_rlbench_env.py", line 188, in reset_to_demo
    self._task.set_variation(d.variation_number)
AttributeError: 'Demo' object has no attribute 'variation_number'

I find the get_stored_demos function in rlbench/utils.py, and it doesn't define 'variation_number'

@zqy-an, are you using my fork of RLBench: https://github.com/MohitShridhar/RLBench/tree/peract ?

You can check by:

import rlbench
print(rlbench.__path__)

['/home/xxx/code/robotics/RLBench/rlbench'] I'm sure RLBench was used. I think the problem is with the get_stored_demos function in rlbench/utils.py

@zqy-an, my guess is the wrong RLBench is being used when running data_generator.py. You can manually open the pickle files and check if the variation number exists.
