我有一个使用pytorch的项目的工作设置。它突然开始引发numpy.core.multiarray导入错误，尽管在此之前一切都很正常。我将粘贴下面的代码部分。
python3

During handling of the above exception, another exception occurred:

解决方案非常简单。我创建了一个名为random.py的文件，然后numpy尝试将其作为系统随机导入，当然这是行不通的。重命名/删除此文件可修复错误。
如果您遇到与我相同的错误，请尝试使用第二部分import numpy.core.multiarray进行调试。如果它引发了任何明显的错误，请尝试修复这些错误。否则，互联网上建议的重新安装/版本更改可能会有所帮助。
