類型錯誤使用SORL-縮略圖和枕頭

Question

IM使用SORL-縮略圖Django和我發現了一個錯誤：

TypeError: integer argument expected, got float 

我不知道這是否是一個SORL-縮略圖錯誤或枕頭錯誤。 我也不知道哪個參數失敗。我怎麼解決這個問題？ 我應該開始調試嗎？

謝謝！

編輯1：

發起者debbugin和最後的參數是：

encoder = <built-in function jpeg_encoder> 
args = ('RGB',) 
mode = 'RGB' 
encoder_name = 'jpeg' 
extra = (95, True, 0, True, 0, 0.0, 0.0, -1, None, '', '') 

編輯2： 在/usr/local/lib/python2.7/dist-packages/PIL/Image。 PY在保存在行1685： save_handler（個體經營，FP，文件名） - 參數是：

fp = <cStringIO.StringO object at 0x7f0d4f3ae688> 
format = 'JPEG' 
self = <PIL.Image.Image image mode=RGB size=75x21 at 0x7F0D4F2079E0> 
filename = '' 
ext = '' 
params = {'compression': 0, 'dpi': (0.0, 0.0),'optimize': 1, 'progressive': True, 'quality': 95} 
close = 0 
save_handler = <function _save at 0x7f0d4f13d230> 

他們看起來正常的我，也許是一個枕頭錯誤。

Answer 1

實測值的原因：

文件類型：PC位圖，Windows 3.X的格式，285 X 78×24 MIME類型：image/X-MS-BMP 建議的文件擴展名（多個）：BMP

該文件是BMP，而不是JPG。

對不起。
