Python Wand生成大量临时文件

We use Python Wand under Celery to process a lot of pictures. On some of our servers, our treatment sometimes leaves a lot of temporary files behind, e.g.:

我们在芹菜下面用Python棒处理很多图片。在我们的一些服务器上，我们的处理有时会留下很多临时文件，例如:

$ ls -lh /tmp/ -rw------- 1 ubuntu ubuntu 1.9M Apr 1 04:35 magick-y1yKKiVZ -rw------- 1 ubuntu ubuntu 1.9M Apr 1 04:41 magick-Y22P6McK -rw------- 1 ubuntu ubuntu 1.9M Apr 1 04:37 magick-YaaSIYrk -rw------- 1 ubuntu ubuntu 1.9M Apr 1 04:39 magick-YEkn4H15 -rw------- 1 ubuntu ubuntu 1.9M Apr 1 04:39 magick-yf2Vrfwi -rw------- 1 ubuntu ubuntu 1.9M Apr 1 04:38 magick-YIYTaArn -rw------- 1 ubuntu ubuntu 199K Apr 1 04:43 magick-YLM5wYm9 -rw------- 1 ubuntu ubuntu 199K Apr 1 04:43 magick-YLo5SeVp [...]

$ ls lh / tmp / - - - - - - - - 1 ubuntu ubuntu 1.9 m 4月1日04:35 magick-y1yKKiVZ - - - - - - - - 1 ubuntu ubuntu 1.9 m 4月1 04:41 magick-Y22P6McK - - - - - - - - 1 ubuntu ubuntu 1.9 m 4月1 04:37 magick-YaaSIYrk - - - - - - - - 1 ubuntu ubuntu 1.9 m 4月1 04:39 magick-YEkn4H15 - - - - - - - - 1 ubuntu ubuntu 1.9 m 4月1 04:39 magick-yf2Vrfwi - - - - - - - - 1 ubuntu ubuntu 1.9 m 4月1 04:38 magick-YIYTaArn - - - - - - - - 199 k 4月1 ubuntu ubuntu有magick-YLM5wYm9 - - - - - - - - 199 k 4月1 ubuntu ubuntu有magick-YLo5SeVp[…]

Is there a way to make Wand clean up after it worked on some file? If it's the expected behavior, is there a way to debug this and know which image created which temp file, by putting a log statement for example?

有没有一种方法可以让魔杖在处理一些文件后清理掉?如果它是预期的行为，是否有一种方法来调试它，并通过放置一个日志语句，知道哪个映像创建了哪个temp文件?

Thanks

谢谢

Easy way: In your environment settings point MAGICK_TMPDIR=/home/somewhere and rm magick-* that folder in your crontab.

简单方法:在您的环境设置中，指向MAGICK_TMPDIR=/home/somewhere和rm magick-* crontab中的文件夹。

Hard way: Apply this path to ImageMagick before compiling:

硬方法:在编译之前将此路径应用于ImageMagick:
