Pickle file loading issue #1

Open eshafeeqe opened 3 years ago

Dear @rafaelpossas

Thanks for the code. I was trying your code for running an experiment but it seems pickle file is not loading properly. I am getting following error. 

Traceback (most recent call last):
  File "/home/rl_tests/domain_randomization/bayes_sim/pendulum_param_inference.py", line 11, in <module>
    g = PendulumDataGenerator(policy_file=policy_file, load_from_file=False)
  File "/home/rl_tests/domain_randomization/bayes_sim/src/data/pendulum_data_generator.py", line 31, in __init__
    self.policy = PPO2.load(policy_file)
  File "/home/.virtualenvs/bysim_env/lib/python3.6/site-packages/stable_baselines/common/base_class.py", line 938, in load
    data, params = cls._load_from_file(load_path, custom_objects=custom_objects)
  File "/home/.virtualenvs/bysim_env/lib/python3.6/site-packages/stable_baselines/common/base_class.py", line 689, in _load_from_file
    data, params = BaseRLModel._load_from_file_cloudpickle(load_path)
  File "/home/.virtualenvs/bysim_env/lib/python3.6/site-packages/stable_baselines/common/base_class.py", line 623, in _load_from_file_cloudpickle
    data, params = cloudpickle.load(file_)
_pickle.UnpicklingError: invalid load key, 'v'.
Current Directory: /home/rl_tests/domain_randomization/bayes_sim

I am using cloudpickle version of 0.8.0. Any help in this is really appreciated.

Hi Shafeeq,

The Pickle files are stored with Git LFS, you need to enable it and tell it to download the files, you probably have the placeholders for now

Regards
