使用Anaconda在Spyder中运行OpenAI Gym中几乎所有代码(例如此代码:https://gym.openai.com/evaluations/eval_y5dnhk0ZSMqlqJKBz5vJQw),我遇到了以下错误信息:
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'.
然而当我在终端中输入brew install ffmpeg
时,会得到Warning: ffmpeg-3.2 already installed
的警告,并且没有任何反应。
有没有什么解决这个错误的想法?
