Question

我在文件夹中有一些图像，如果它们的尺寸不是我想要的，我将它们复制到另一个文件夹，然后使用thumbnail命令调整它们的大小。在我完成之后，我想重命名它们，并且作为新名称的一部分，我想要包含像素大小。

无论如何，我已经尝试了我的代码，并遇到以下错误：

File "C:/Anaconda/PhD/Scikit-Learn/Image Resizing3.py", line 55, in resize_img
os.rename(image_directory + '/Resized'+ "/" + image_filenames[i],image_directory + '/Resized'+ "/" + image_filenames[i][0:(len(image_filenames[i])-4)]+ str(img1.size[0]) + ' x ' + str(img1.size[1]) + '.jpg' )

PermissionError：[WinError 32]进程无法访问该文件，因为它正由另一个进程使用：

我想如果我使用with关键字，它会关闭我正在使用的任何进程。如果有人能在我的代码中看到任何问题，那么如果您有解决方案，我真的很感激。

解决了它，我使用了shutil.move而不是os.rename。

Python权限错误[WinError32] ...被另一个进程使用
