Win10系统 安装Anaconda+TensorFlow+Keras
参考：https://www.cnblogs.com/zeroingToOne/p/8407059.html

之后自己安装scikit-learn运行程序出现如下错误

Using TensorFlow backend.
RuntimeError: module compiled against API version 0xc but this version of numpy is 0xb
ImportError: numpy.core.multiarray failed to import
ImportError: numpy.core.umath failed to import
ImportError: numpy.core.umath failed to import

尝试网上各种方法都没有效果，灵感来自于：https://blog.csdn.net/qq_22230583/article/details/83063949

大概是因为numpy的版本不对，于是
打开anaconda prompt
分别进行下面两步

1；原始环境下输入：pip install --upgrade --ignore-installed tensorflow

2；tensorflow环境下输入：pip install --upgrade --ignore-installed tensorflow

然后完美解决！！！
