TypeError error and blank web while running with keras 1.2.1

[madi171]

When I run python api.py, and start keras program with remote callbacks, I got these message:

I checked my gevent and flask version:

• gevent1.0.2
• flask0.10.1

So I modifed api.py like these:

@app.route("/publish/epoch/end/", methods=['POST'])
def publish():
    #payload = request.form.get('data')
    payload = unquote(request.data.split('=')[1]).replace('+','')
    try:
        data = json.loads(payload)
    except:
        return {'error':'invalid payload'}

    def notify():
        msg = str(time.time())
        for sub in subscriptions[:]:
            sub.put(payload)

    gevent.spawn(notify)
return "OK"

Then everything goes OK

This is awesome thanks for sharing. This helped me get it to work. I believe there are two things we need to add here to make it work.

from urllib import unquote

and

@app.route("/publish/epoch/end/", methods=['POST'])
def publish():
    #payload = request.form.get('data')
    payload = unquote(request.data.split('=')[1]).replace('+','')
    try:
        data = json.loads(payload)
    except:
        return {'error':'invalid payload'}

    def notify():
        msg = str(time.time())
        for sub in subscriptions[:]:
            sub.put(payload)

    gevent.spawn(notify)
    return "OK"

Thanks for the tip. But on one of my configs (WinPython/Python 3.5.2) I had to slightly modify the payload formatting line to add utf-8 decoding:

payload = unquote(request.data.decode("utf-8").split('=')[1]).replace('+','')

Great, thank you!

from urllib import unquote
that import was changed in the newest version of urllib to:
from urllib.parse import unquote
