SubprocVecEnv not receiving any data

I have a problem similar to issue #640

For a long time it worked without any problem and now the code get’s stuck in the initilization of the SubprocVecEnv. The line with causes the problem is:

observation_space, action_space = self.remotes[0].recv()

There it gets stuck without any problem. it just receives no data… The problem occurs with any anvironment. I want to use the SubprocVecEnv and not the DummyVecEnv.

I am on windows 10 with the following packeges: ` Package Version

@DavidS32 I’m almost sure this is something related to your computer config. It seems that you are using anaconda. Please try to create a fresh new environment like this:

conda create -n new_env tensorflow-gpu==1.15 cloudpickle~=1.2.0

Then install baselines on the anaconda env. with pip. I have just tested this on windows10 and it works (github master branch). If it doesn’t work for you you can also check your firewall/antivirus software. Hope this helps.

Hmmm… indeed it works! Thank you very much 😄
