我对 Unity 有点陌生，所以我可能做错了什么。但我确实从头到尾遵循了安装指南，可以在 mlagents GitHub 安装指南中找到。我的猜测是我在部分 python 包安装中做错了，尽管我也遵循了这一点。但是，当我尝试mlagents-learn config/ppo/3DBall.yaml --run-id=first3DBallRun在 cmd 中运行 mlagents-learn 命令时，出现以下错误。

鉴于错误消息，我假设问题出在 Python 上。还有快速笔记，我不在虚拟环境中，不确定这是否重要。我只是想为一个论文项目做一些简单的测试。还有一种方法可以从培训课程中提取图表吗？
