numpy报错：ValueError: numpy.ufunc size changed, may indicate binary incompatibility.

今天使用numpy结合sklearn绘制曲线的时候发现抱错：

D:\Yolov3_Tensorflow\python\python.exe C:/Users/HuaWei/Desktop/绘制不同光照条件下识别率曲线图/plot.py
Traceback (most recent call last):
  File "C:/Users/HuaWei/Desktop/绘制不同光照条件下识别率曲线图/plot.py", line 14, in <module>

  File "__init__.pxd", line 918, in init sklearn.utils.murmurhash
ValueError: numpy.ufunc size changed, may indicate binary incompatibility. Expected 216 from C header, got 192 from PyObject

Process finished with exit code 1

可能是之前安装tensorflow的时候它自动安装了老版本的，查看当前numpy版本：

C:\Users\HuaWei>pip install numpy
Requirement already satisfied: numpy in d:\yolov3_tensorflow\python\lib\site-packages (1.15.1)

C:\Users\HuaWei>

卸载numpy重新安装一下试试：

C:\Users\HuaWei>pip install -i https://pypi.tuna.tsinghua.edu.cn/simple numpy

完美，没再报错了，但是就是不知道tensorflow那边会怎么样。。。
