Numpy报错:ImportError: numpy.core.multiarray failed to import

导入自定义的 python 模块时,出现以下报错:

ImportError: numpy.core.multiarray failed to import
    from .cv2 import *
ImportError: numpy.core.multiarray failed to import

原因:

numpy 版本过低或者过高

解决:

  • 查看numpy 版本: pip show numpy
    我当前环境中的 numpy 版本是: Version: 1.16.5
  • 升级: pip install -U numpy
(tensorflow) Robin-macbook-pro:~ robin$ pip install -U numpy

    Uninstalling numpy-1.16.5:

结果还是不行,遂给 numpy 降级: pip install -U numpy==1.14.0(之前是 1.16.5

不仅造成了不少冲突,而且没效果:

还是不行:

将numpy更到最新版本: pip install -U numpy
同时更新 opencv 的版本试试,这是当前版本:

Numpy报错:ImportError: numpy.core.multiarray failed to import
本身就是最新版本,尝试过没用。

Numpy报错:ImportError: numpy.core.multiarray failed to import后来发现,问题在于
  • import numpy as numpy
    会报错: ImportError: numpy.core.multiarray failed to import
  • import cv2
    会报错: AttributeError: module 'logging' has no attribute 'Handler'

最后发现,最为离奇诡异的是,在不同的文件夹下面执行相同的代码( import numpy as np)是没有任何问题的

(1)

/Users/robin/software/anaconda3/envs/tensorflow/bin/python3.6 /Users/robin/MLcode/Pycharm_Project/tensorflow/2021/0823_face_recognition_environment/test.py

    class _CapturingHandler(logging.Handler):
AttributeError: module 'logging' has no attribute 'Handler'

最后我放弃治疗了,新建了一个文件夹,将文件移动过去了,就当做 Pycharm 抽风了吧

浪费一下午时间…!!!!
