Wrong [no-member] errors while members being detected

Media is cool. ™


Well, as you see, the problem is, while the `wx` module member (e.g. the class) is detected, but it will show me this frustrating error. The error persists if I use the format of `from wx import Frame`. Amazingly, the autocompletion works (almost) fine, both for classes like `Frame` and their methods (e.g. `frame.SetFocus()`).

Perhaps this is an upstream bug, but not really sure about that, so I opened the issue here.

Note that, I tested the issue both with default and customized settings of the package, but none of them worked.

### Environment
- OS: Fedora Workstation 34
- Atom: v1.58.0 (AppImage)
- Tested package versions: 1.8.0, 1.9.3, 1.9.6

在 Atom v1.58.0 中使用 ide-python 1.8.0、1.9.3 和 1.9.6，复现针对 wx 成员和 `from wx import Frame` 的 [no-member] 诊断，并将其与报告中可正常工作的自动补全进行比较。未指定任何仓库文件或测试；完成条件是确定该诊断属于此软件包还是上游组件，并记录经过验证的修复或上游调查结果。
