问题描述

我正在尝试研究神经网络和深度学习(http://neuralnetworksanddeeplearning.com/chap1.html)。使用MichalDanielDobrzanski为Python3更新的版本(https://github.com/MichalDanielDobrzanski/DeepLearningPython)。我试图在我的命令控制台中运行它，但它给出了下面的错误。我试着卸载并重新安装setupTools、Theano和NumPy，但到目前为止都没有成功。如有任何帮助，不胜感激！！

以下是完整的错误日志：

解决方案

我遇到了同样的问题，通过以下方式解决了将NumPy降级到1.20.3版本的问题：

pip3 install --upgrade numpy==1.20.3
