Anaconda 在 spyder 中运行 OpenAi gym 的几乎所有代码(例如此代码:https ://gym.openai.com/evaluations/eval_y5dnhk0ZSMqlqJKBz5vJQw )我遇到以下错误消息:
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'.
但是,当我输入brew install ffmpeg
终端时,我得到Warning: ffmpeg-3.2 already installed
并且没有任何反应。
有关如何解决此错误的任何想法?
