模块numpy.distutils.__config__没有属性“blas_opt_info”
我试着研究神经网络和深度学习(http://neuralnetworksanddeeplearning.com/chap1.html).使用MichalDanielDobrzanski (https://github.com/MichalDanielDobrzanski/DeepLearningPython)为Python3更新的版本。尝试在我的命令控制台中运行它，它在下面给出了一个错误。我尝试过卸载和重新安装setuptools、theano和numpy，但到目前为止还没有一个能工作。任何帮助都是非常感谢的！
以下是完整的错误日志：

我也遇到了同样的问题，并通过以下方式将numpy降级为1.20.3版本：

Monkey-修补NumPy.
import numpy as np
try:
np.distutils.__config__.blas_opt_info = np.distutils.__config__.blas_ilp64_opt_info
except Exception:
pass这个工作片段直接来自NumPy维护者拉尔夫·戈默斯(@rgommers)，他首先定义了一个子模。然后，提交人Alex Rogozhnikov (@arogozhnikov)通过子模块代替对其进行了改进。
对于主动维护的软件(我要说的是...so，而不是theano )，相反：
- 需要NumPy≥1.22.0。
- 全局地将对
np.distutils.__config__.blas_opt_info的所有中断引用替换为对np.distutils.__config__.blas_ilp64_opt_info的工作引用。
危险威尔·罗宾逊！危险！
然而，所有这些都附带了一个重要的警告：所有这些都将再次打破的，在未来的一些尚未决定的NumPy发布中。为什么？引用NumPy维护者拉尔夫·戈默斯(@rgommers) https://github.com/numpy/numpy/issues/21079#issuecomment-1043862232的话
当我们改变构建系统时，这一切都会改变，我们不会保留
system_info类型的输出。

其他信息：
theano是一个过时的软件包，不能与numpy的现代版本一起使用。然而，一些遗留代码库将使用theano，因此需要解决将numpy < 1.22降级的方法，就像接受的答案一样。否决是在numpy 1.22中进行的:请参见numpy问题#21079。
如果您需要坚持使用numpy 1.22+，那么blas_opt_info位于numpy.distutils.system_info.blas_opt_info中，因此手动修补theano以使用正确的符号将是另一种解决方法。
