我使用 Python（版本 3.11.5）和 Anaconda 发行版。我通过 Anaconda 安装 OpenCV（版本 4.6.0）和 GStreamer（版本 1.18.5）包。我有读取视频帧的代码：
Import cv2
Import matplotlib.pyplot as plt
video = cv2.VideoCapture(r"file_name.mov")
number_of_frames = int(video.get(cv2.CAP_PROP_FRAME_COUNT))
print("Number of frames: ", str(number_of_frames))
video.set(cv2.CAP_PROP_POS_FRAMES, frame_id)
ret, frame = video.read()
img = np.asarray(cv2.cvtColor(frame, cv2.COLOR_BGR2RGB))
fig, axs = plt.subplots()
axs.imshow(img, origin='lower')
plt.show()
代码可以正常运行（在另一台电脑上），但在我的电脑上运行不佳。我在 Windows 11 上使用 Visual Studio Code 运行。通常情况下，代码可以在 10 秒内运行，但对于我的计算机，我收到警告并使用了 7 分钟多的时间来运行它（正常结果）。警告是：

我尝试寻找这样的问题的解决方案，但我仍然找不到。我真的需要大家的帮助来解决这个问题。非常感谢。
我通过卸载 Anaconda 和 Python 解决了这个问题。然后再次从 https://www.python.org/ 安装 python。并在 Windows 的命令提示符中使用
pip install [libraries-name]
