ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
numba 0.56.2 requires setuptools<60, but you have setuptools 65.5.1 which is incompatible.
pip uninstall setuptools
pip install setuptools==41.1.0
再装tensorflow

但是实际版本还是65
卸载再装
版本对了：
然后：
然后再show又变成了：
怀疑装tensorflow的命令会让setuptools的版本变成65
果然找到了：
然后发现其实已经有tensorflow，就算有报错，就算setuptools的版本是65
所以，pip就是装好了tensorflow，但出了一个报错说setuptools的版本是65不行，然后去降低版本后回来装tensorflow，装tensorflow又会自动把版本变成65，循环往复
