最近学习分类数据，想试试tensorflow，于是…

环境：win10(mac电脑装的win10)，python3.7，pycharm

直接pip install tensorflow之后，import tensorflow报错

(tensorflow好像是2.1)

搜了各种帖子，有的说用pip3 install tensorflow的，试了一下还是不行

有的说要装 Microsoft Visual C++ 2015 Redistributable ，我看我电脑装了2017的，专门卸了2017装2015，还是报错，而且是报找不到MSVCP140_1.dll

于是下载装了Microsoft Visual C++ 2015-2019 Redistributable，出其不意的tensorflow竟然可以用了

虽然还是报warnning

看了一下好像是因为我不是n卡用不了cuda，但是cpu应该是能用，就没管了

希望能帮助同样遇到问题的朋友！
