A Simple PyTorch deep learning REST API

This repository contains the code of 如何用flask部署pytorch模型

Starting the pytorch server

python run_pytorch_server.py 

You can now access the REST API via http://127.0.0.1:5000/predict

Submitting requests to pytorch server

python simple_request.py --file='file_path'

deploy-pytorch-model's Issues

hello！I meet some problems when trying to test dog.jpg

File "simple_request.py", line 38, in
predict_result(args.file)
File "simple_request.py", line 20, in predict_result
r = requests.post(PyTorch_REST_API_URL, files=payload).json()
File "D:\ananconda\lib\site-packages\requests\models.py", line 885, in json
return complexjson.loads(self.text, **kwargs)
File "D:\ananconda\lib\json_init_.py", line 354, in loads
return _default_decoder.decode(s)
File "D:\ananconda\lib\json\decoder.py", line 339, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "D:\ananconda\lib\json\decoder.py", line 357, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

thank you for your help!
