I got this kind of error during a POST

Thanks a lot for your help

The errors comes with Python post :

r = requests.post(url, data=param, files={'file': open(img_path, 'rb')})

It works with cURL:

curl URL -F "file=@test/test_imgs/sushi.jpg" -F "model=default"

I verified. Indeed, with python-requests, there is no content-type header. Cf http://docs.python-requests.org/en/master/user/quickstart/, section Post a multipart-encoded file. To have the content type, it is optional with the following syntax :

url = 'http://httpbin.org/post' files = {'file': ('report.xls', open('report.xls', 'rb'), 'application/vnd.ms-excel', {'Expires': '0'})} r = requests.post(url, files=files)

So it might be good to have the server work without content type header.
