下降将OpenCV应用于Python上，以避免某些错误

Question

我在python上应用OpenCV，遵循官方https://github.com/opencv/opencv-python提供的指南。我更新了pip，并在命令单元格中输入了pip install opencv-contrib-python。一开始，代码顺利运行.However，大约10分钟后，出现了一个错误。

报告的第一部分如下：

ERROR: Exception:
Traceback (most recent call last):
  File "D:\app\Anaconda3\lib\site-packages\pip\_vendor\urllib3\response.py", line 435, in _error_catcher
    yield

  File "D:\app\Anaconda3\lib\ssl.py", line 1099, in read
    return self._sslobj.read(len, buffer)
socket. Timeout: The read operation timed out

我还附上了第二个错误部分。

During handling of the above exception, another exception occurred:

其中，“D：\app\ Anaconda 3”是我的Anaconda所在的地方。

我想知道怎么会有很多错误。此外，我也渴望在我的python上正确地应用Opencv

如果有人能解决我的困惑，并给出一些关于申请的建议，我会很感激的。

谢谢！

我解决了问题！这是由于我的地区。从国外下载这些包裹需要更多的时间。我成功地重新下载了这个软件包。
