Keras predict not returning inside celery task

Question

Following Keras function (predict) works when called synchronously

pred = model.predict(x)

But it does not work when called from within an asy

Answer 1

I got the reference from this Blog

• Tensorflow is Thread-Specific data structure that are working behind the scenes when you call model.predict

GRAPH = tf.get_default_graph()
with GRAPH.as_default():
    pred = model.predict
return pred

But Celery uses processes to manage all its worker pools. So at this point, things are still not working on Celery for that you need to use gevent or eventlet library

pip install gevent

now run celery as :

celery -A mysite worker --pool gevent -l info
