报错 cannot import name ‘int‘ from ‘numpy‘

报错详情：

原因是因为np.int在numpy1.20已经被废弃掉了，可以通过

pip show numpy

在命令行里查看。

现在使用的是np.int_ 或者 np.int32 或者 np.int64

猜测原因

但这个报错是在我自己的site-packages里的numpy的报错，我怀疑可能是numpy本身的问题，所以通过命令

pip uninstall numpy

把这个numpy给uninstall了

大致方法流程：

1. uninstall numpy
2. 然后删掉numpy的whl文件，再去python扩展包网页下载一个版本匹配的whl文件
3. 把whl文件放在script文件夹里面，然后通过pip install numpy-xxxx.whl安装numpy

具体：

1.如何选择下载哪一个呢？

使用命令：

pip debug --verbose

查看当前python支持的版本

重点关注后面的，就是支持的版本的名称，也就是后面whl文件你要修改的名字

  cp38-cp38-win_amd64  cp38-abi3-win_amd64  cp38-none-win_amd64  cp37-abi3-win_amd64  cp36-abi3-win_amd64  cp35-abi3-win_amd64  cp34-abi3-win_amd64  cp33-abi3-win_amd64  cp32-abi3-win_amd64  py38-none-win_amd64  py3-none-win_amd64  py37-none-win_amd64  py36-none-win_amd64  py35-none-win_amd64  py34-none-win_amd64  py33-none-win_amd64  py32-none-win_amd64  py31-none-win_amd64  py30-none-win_amd64  cp38-none-any  py38-none-any  py3-none-any  py37-none-any  py36-none-any  py35-none-any  py34-none-any  py33-none-any  py32-none-any  py31-none-any  py30-none-any

这些都是可以下载的版本
因为我python版本是3.8.3，所以我选择的是

38代表python版本，64代表64位

2.修改文件名：

如果文件名不规范，不符合上面支持的格式，在pip install numpy-xxx.whl时就会出现

numpy-1.19.5+mkl-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.

这样的的报错

改成这样就好啦：保证最后的cp38-cp38-win_amd64在上面支持的格式中出现

3.安装whl文件：

出现Successfull installed就安装好啦！

用python验证一下：或者直接输入python，我这里是指定了python。

然后就没有那个错误啦！
