Running almost every code from OpenAi gym in spyder by Anaconda (for instance this code: https://gym.openai.com/evaluations/eval_y5dnhk0ZSMqlqJKBz5vJQw ) I run into the following error message:
DependencyNotInstalled: Found neither the ffmpeg nor avconv executables. On OS X, you can install ffmpeg via 'brew install ffmpeg'. On most Ubuntu variants, 'sudo apt-get install ffmpeg' should do it. On Ubuntu 14.04, however, you'll need to install avconv with 'sudo apt-get install libav-tools'.
However when I type brew install ffmpeg in terminal, I get Warning: ffmpeg-3.2 already installed and nothing happens.
Any ideas on how to fix this error?
You need to install a copy of ffmpeg that can be recognized by Anaconda. Please run this command in a terminal to do that
conda install -c conda-forge ffmpeg
