I have a saved model that I can generate a prediction when I run it on the main thread. When I try to use the same function in a thread I get the following error.

Note a summary of my code will be pasted after the error.

Exception in thread Thread-6:

The model is loaded into memory when I start running the code. To do this I created a globals object that loads the model the following way.

self.ModelName = ModelName

self.Model = load_model("Models/" + self.ModelName + '.mdl')

self.Model._make_predict_function()

To use the predict function it is run in a thread

predict = self.Model.predict(data, steps=10)

I know the data supplied is correct for I get a result if I just cut out the threading aspect out of my code and make my code into a single thread.

I cut out most of code since its split up into multiple files and as I tried to paste here stack overflow told me I had to much code.

If needed please let me know which sections of code would be most beneficial to post in as an edit.
