问题：

出现此错误是因为numpy版本不正确/不兼容。众所周知，大多数机器学习和深度学习库都在Numpy之上。像cv2、matplotlib、PyTorch、pyinstaller等Python模块也是其中之一。当我们从它们中安装任何模块时，它会自动安装require NUMPY版本。但是当我们在它之后安装另一个包时，另一个模块可能会根据兼容的依赖关系更改NUMPY的版本。现在下次导入上一个模块时，可能会出现此错误。

解决：

numpy的版本的问题，升到1.8.0以上OK了。

解决此错误的直接方法是将现有的numpy模块更新到numpy 1.8.0或更高。升级numpy的方法很多。

pip uninstall numpy

pip install numpy==1.8.0
