Uploading file to Flask app using curl not working [duplicate]

Question

I am trying to upload a file to a Flask app and use it as a pandas DataFrame, not store it. I have a Flask app with the following endpoint: ```

@app.route('/upload_file/', methods=['POST'])
def upload_file():

        afile = request.files['file']
        ff = file.read(afile)
        print ff

        return str(ff)
```
I am trying to use curl to use POST to upload the file using:

```curl -v -F file='/Users/asharma/../cpr_all_platforms.csv' http://127.0.0.1:5000/upload_file/```

I get the following error:

```
*   Trying 127.0.0.1...

@app.route('/upload_file/', methods=['POST'])
def upload_file():

        file = request.files['file']

        ff = pd.read_csv(file)

        return str(ff)

The endpoint is hit using curl and the filename:

curl -i -X POST -F file=@/Users/asharma/../cpr_all_platforms.csv http://127.0.0.1:5000/upload_file/
