Cartpole error message #124

Closed sunchipsster1 closed 4 years ago

sunchipsster1 commented 4 years ago

Hello all! I was wondering if anyone knows how to resolve the following error message? This is taken from the Cartpole colab without changing any of the code. Does the dqn_config = ... need any values, or is it meant to be left without assignment? Thank you!

hi, apologies for this, it's due to our recent switch to keras, thanks for pointing it out. i will be resolving this in the next few days. i'll report on this thread once it's resolved, apologies for the inconvenience.

Thank you so much for the kind help! I do not know if the following is another instance of the recent switch to keras, but here is another error message, encountered in the "Agents" colab kindly provided by Dopamine--> keyError 'Asterix'

i just pushed a new version of dopamine to pypi and i believe the cartpole issue should be resolved now. can you try again and make sure that it installs version 3.0.1 of dopamine-rl? i'm taking a look at the agents colab now.

i just tried the agents colab and it seems to work. the KeyError you're getting is likely because you haven't run any of the colab's agents on Asterix.
