python - PIL - 不是有效数量的量化表。应该在 2 到 4 之间

Question

我的 PIL 库有一段时间工作正常，但现在我到处都遇到这个异常，如何解决这个问题？

f = "/media/bighdd/1.jpg"
from PIL import Image
im = Image.open(f)
im.thumbnail('50x50')
im.save('/media/bighdd/2.jpg')

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 1437, in save
    save_handler(self, fp, filename)
  File "/usr/local/lib/python2.7/dist-packages/PIL/JpegImagePlugin.py", line 471, in _save
    ImageFile._save(im, fp, [("jpeg", (0,0)+im.size, 0, rawmode)])
  File "/usr/local/lib/python2.7/dist-packages/PIL/ImageFile.py", line 494, in _save
    for e, b, o, a in tile:
ValueError: Not a valid numbers of quantization tables. Should be between 2 and 4.

检查您是否以这种方式导入图像:

from PIL import Image

我在代码中遇到了同样的错误

import Image

这个微小的变化让事情发生了变化
