Saving to logs/ppo2/BipedalWalkerHardcore-v2_2
looking at your stack trace, the model was saved in that folder. I should add a warning, even though you get a seg fault, saving is working.
This is my google colab file
https://colab.research.google.com/drive/1dnROnz1kDQsHI4ReTjjF79EnHc3GlvKd
For some reason I cannot seem to save any trained model in google colab. It is giving some kind of segmentation error. The initial part of the file is the same as the template google colab file and the version of stable baselines is the latest as I am updating the stable baselines version.
However on trying to save it is giving this error. !python train.py --algo ppo2 --env BipedalWalkerHardcore-v2 -f logs -n 10000 ========== BipedalWalkerHardcore-v2 ========== OrderedDict([('cliprange', 'lin_0.2'), ('ent_coef', 0.001), ('gamma', 0.99), ('lam', 0.95), ('learning_rate', 'lin_2.5e-4'), ('n_envs', 16), ('n_steps', 2048), ('n_timesteps', 100000000.0), ('nminibatches', 32), ('noptepochs', 10), ('normalize', True), ('policy', 'MlpPolicy')]) Using 16 environments Normalizing input and return WARNING:tensorflow:From /usr/local/lib/python3.6/dist-packages/stable_baselines/common/policies.py:436: flatten (from tensorflow.python.layers.core) is deprecated and will be removed in a future version.

I want to save the logs folder on to my google drive or at least find a way to download them into my computer. But in this case I cannot even seem to save the file onto log it seems.
