PyQt5导入错误上的Pycharm调试器错误

Question

我无法再在Pycharm中进行调试，因为我不断收到以下错误：

Connected to pydev debugger (build 192.5728.105)
C:\ProgramData\Anaconda2\envs\ListManagement\lib\site-packages\sklearn\ensemble\weight_boosting.py:29: DeprecationWarning: numpy.core.umath_tests is an internal NumPy module and should not be imported. It will be removed in a future NumPy release.

ImportError: DLL load failed: Access is denied.

我已经安装了最新版本的PyCharm，但仍然出现相同的错误。 另外，我仅在调试时收到此错误。 如果我要运行脚本，它将可以正常运行。
