KERAS LSTM Live Issue

Hello,

Im having issues with the life execution of the LSTM Model. The think is really odd, because, the algo works perfectly and runs without any issue in for the Backtests.

The thing is, that whenever I try to deploy it, this error appears.

2021-11-02 06:27:58 :Runtime Error: ValueError : Tensor Tensor("dense_1/BiasAdd:0", shape=(?, 1), dtype=float32) is not an element of this graph. at _as_graph_element_locked raise ValueError("Tensor %s is not an element of this graph." % obj) File "ops.py" in ops.py: line 3685 : StackTrace: ValueError : Tensor Tensor("dense_1/BiasAdd:0", shape=(?, 1), dtype=float32) is not an element of this graph. at _as_graph_element_locked raise ValueError("Tensor %s is not an element of this graph." % obj) File "ops.py" in ops.py: line 3685

I don't know exactly what may cause this issue, do you have any idea, of what might be going on?

Hi Álvaro Anton Blanco,
We call the model inside a scheduled event that runs on a separate thread during live trading in the above algorithm.
We suggest trying to address the issue using the features of the following snippet that we have found on https://github.com/keras-team/keras/issues/10431.

import keras
import tensorflow as tf
model = keras.models.load_model(<model_file>)
model._make_predict_function()
graph = tf.get_default_graph()

def some_route(...):
	...
	global graph
	with graph.as_default():
		outputs = model.predict(inputs)
	...

For issues with live trading, please get in touch with support@quantconnect.com with the live deployment attached.
Best,
Varad Kabade

Don't worry.

If they haven't answered yet, then they are busy with other things.

BTW. You have not responding to my answer on your question for 17 days.
