How to use a trained learning model (.sav) in ROS python node?

edit

Hello,

I created a learning model (by MLP method) by using the Jupyter notebook. Now, I want to use it in a ROS python node. How I can load the trained model?

In Jupyter notebook, I can use the following code to load a trained model:

# load the model from disk
1) filename = r"C:\Users\....\TrainedModelName.sav"
2) loaded_model = pickle.load(open(filename, 'rb'))

However, by using code line 1 in the ROS python node, I receive the error. (I changed the address according to the Ubuntu directory)
