今天使用numpy結合sklearn繪制曲線的時候發現抱錯：

D:\Yolov3_Tensorflow\python\python.exe C:/Users/HuaWei/Desktop/繪制不同光照條件下識別率曲線圖/plot.py Traceback (most recent call last):File "C:/Users/HuaWei/Desktop/繪制不同光照條件下識別率曲線圖/plot.py", line 14, in <module>from sklearn.linear_model import LinearRegressionFile "D:\Yolov3_Tensorflow\python\lib\site-packages\sklearn\__init__.py", line 82, in <module>from .base import cloneFile "D:\Yolov3_Tensorflow\python\lib\site-packages\sklearn\base.py", line 20, in <module>from .utils import _IS_32BITFile "D:\Yolov3_Tensorflow\python\lib\site-packages\sklearn\utils\__init__.py", line 22, in <module>from .murmurhash import murmurhash3_32File "__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 PyObjectProcess finished with exit code 1

可能是之前安裝tensorflow的時候它自動安裝了老版本的，查看當前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>

卸載numpy重新安裝一下試試：

C:\Users\HuaWei>pip install -i https://pypi.tuna.tsinghua.edu.cn/simple numpy Looking in indexes: https://pypi.tuna.tsinghua.edu.cn/simple Collecting numpyDownloading https://pypi.tuna.tsinghua.edu.cn/packages/53/74/b997e4c7b4abc668e99f4c3dba87ee2c6f7559319af756cc1ede37665a8d/numpy-1.18.1-cp36-cp36m-win_amd64.whl (12.8 MB)|████████████████████████████████| 12.8 MB 3.3 MB/s Installing collected packages: numpy Successfully installed numpy-1.18.1C:\Users\HuaWei>

完美，沒再報錯了，但是就是不知道tensorflow那邊會怎么樣。。。

參考文章：Python導入包時出現“numpy.ufunc size changed, may indicate binary incompatibility”錯誤

總結

以上是生活随笔為你收集整理的numpy报错：ValueError: numpy.ufunc size changed, may indicate binary incompatibility.的全部內容，希望文章能夠幫你解決所遇到的問題。
