Question

当我使用PyCharm时，突然向我显示下面的ImportError（以及许多其他错误）。我认为没有必要在PyCharm IDE中添加numpy。那你能帮我解决这个问题吗？

我尝试使用其他python版本来解决此问题，但没有帮助。

代码是：

import numpy as np
import time

import sys

S = range(1000)
print(sys.getsizeof(5) * len(S))

D = np.arange(1000)
print(D.size * D.itemsize)

我在上面的代码中遇到此错误：

ImportError: No module named 'numpy.matrixlib'

这是在numpy中安装virtualenv的问题。请参阅this question（Linux）或this question（Windows）以获取有关如何在numpy中安装venv或将非虚拟化运行时与numpy一起使用的说明。已安装。

如何解决ImportError：pycharm中没有名为“ numpy.matrixlib”的模块？
