Hi!
Could you give me the sequence of instructions I should execute to reproduce this?

Answer 2 · 2020-11-03T14:23:51.000Z

Here are the steps I followed on Mac OS Mojave (Version 10.14.3):
Python environment: Anaconda3

Cloned the rl-starter-files repository
cd rl-starter-files
conda install pytorch
pip3 install -r requirements.txt
python3 -m scripts.train.py --algo ppo --env MiniGrid-DoorKey-5x5-v0 --model DoorKey --save-interval 10 --frames 80000

Thanks,
Sunandita

Answer 3 · 2020-11-03T15:58:19.000Z

Thanks! Do you have CUDA? Does it occur everytime or does it seem random?

Answer 4 · 2020-11-03T20:24:46.000Z

It worked correctly only one time out of approximately 20 times that I tried running it.

Answer 5 · 2020-11-03T23:41:12.000Z

I realized that my terminal was using system python3 not the conda python3. Using the conda python3 solved the issue.

Answer 6 · 2020-11-04T07:55:59.000Z

Ha that's great! So I am closing since the issue seems to come from your side.

Answer 7 · 2021-12-08T11:42:29.000Z

I am using conda ( and rechecked the python version) but getting this error

Answer 8 · 2021-12-08T11:46:14.000Z

In My case I solved it by putting everything in training.py inside main
