Matplotlib ImportError：DLL加载失败

Question

在Windows上从pyplot Python包中导入matplotlib时，我收到以下错误回溯。可能是什么原因？

Traceback (most recent call last):
  File "E:\python\matplib.py", line 2, in <module>
    from matplotlib import pyplot as plt

    _check_versions()

    return _bootstrap._gcd_import(name[level:], package, level)
