统一：Mlagentslearn问题

Question

我对Unity有点陌生，所以我可能做错了什么。但是我从头到尾都遵循了安装指南，可以在MLGithub安装指南中找到。我的猜测是，我在python包安装部分犯了一些错误，尽管我也遵循了这一点。 但是，当我尝试在cmd中运行mlagents learn命令mlagents-learn config/ppo/3DBall.yaml --run-id=first3DBallRun时，我得到了以下错误

During handling of the above exception, another exception occurred:

鉴于这些错误消息，我假设问题出在Python上。还有，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。还有没有办法从培训课程中提取图表

Answer 1

您确定已安装所有依赖项吗？我会尝试使用anaconda（或其他虚拟环境）安装mlagents，并检查是否出现相同的错误

我通过Unity Hummingbird沉浸式极限教程https://learn.unity.com/course/ml-agents-hummingbirds学习了Unity ML代理的基础知识，在教程中，他还以一种很好的方式解释了安装选项。我真的可以推荐那门课

在同一课程中，他们将介绍如何使用Tensorboard可视化您的训练。或者在the docs上读到它
