PermissionError: [WinError 32] The process cannot access the file because it is being used by another process
提问by user2885647
My code is for a script that looks at a folder and deletes images that are under a resolution of 1920x1080. The problem I am having is that when my code runs;
我的代码用于查看文件夹并删除分辨率为 1920x1080 的图像的脚本。我遇到的问题是当我的代码运行时；
import os
from PIL import Image
while True:
img_dir = r"C:\Users\Harold\Google Drive\wallpapers"
for filename in os.listdir(img_dir):
filepath = os.path.join(img_dir, filename)
im = Image.open(filepath)
x, y = im.size
totalsize = x*y
if totalsize < 2073600:
os.remove(filepath)
I get this error message:
我收到此错误消息：
Traceback (most recent call last):
File "C:\Users\Harold\Desktop\imagefilter.py", line 12, in <module>
os.remove(filepath)
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\Users\Harold\Google Drive\wallpapers\Car - ABT Audi RS6-R [OS] [1600x1060].jpg'
Just to confirm, Python is the only program running on my computer. What is causing this problem and how do I fix it?
确认一下，Python 是我电脑上唯一运行的程序。是什么导致了这个问题，我该如何解决？

Your process is the one that has the file open (via imstill existing). You need to close it first before deleting it.
您的进程是打开文件的进程（通过im仍然存在）。您需要先关闭它，然后才能删除它。
I don't know if PIL supports withcontexts, but if it did:
我不知道 PIL 是否支持with上下文，但如果它支持：
import os
from PIL import Image
while True:
img_dir = r"C:\Users\Harold\Google Drive\wallpapers"
for filename in os.listdir(img_dir):
filepath = os.path.join(img_dir, filename)
with Image.open(filepath) as im:
x, y = im.size
totalsize = x*y
if totalsize < 2073600:
os.remove(filepath)
This will make sure to delete im(and close the file) before you get to os.remove.
这将确保im在您到达之前删除（并关闭文件）os.remove。
If it doesn't you might want to check out Pillow, since PIL development is pretty much dead.
如果没有，您可能想查看 Pillow，因为 PIL 开发几乎已经死了。

I was running into the same problem, but the error was intermittent. If you are coding your file open/close correctly and still running into this error, make sure you are not synching the files with Dropbox, Google Drive, etc. I paused Dropbox and I no longer see the error.
我遇到了同样的问题，但错误是间歇性的。如果您正确编码打开/关闭文件但仍然遇到此错误，请确保您没有将文件与 Dropbox、Google Drive 等同步。我暂停了 Dropbox，我不再看到错误。

This is basically permission error, you just need to close the file before removing it. After getting the image size info, close the image with
这基本上是权限错误，您只需要在删除之前关闭文件。获取图像大小信息后，关闭图像
im.close()

I also had the issue, in windows [WinError 32]
我也有这个问题，在 Windows [WinError 32]
Solved by changing:
通过更改解决：
try:
f = urllib.request.urlopen(url)
_, fname = tempfile.mkstemp()
with open(fname, 'wb') as ff:
ff.write(f.read())
img = imread(fname)
os.remove(fname)
return img
into:
进入：
try:
f = urllib.request.urlopen(url)
fd, fname = tempfile.mkstemp()
with open(fname, 'wb') as ff:
ff.write(f.read())
img = imread(fname)
os.close(fd)
os.remove(fname)
return img
