sanfis/helpers.py: AttributeError: 'numpy.ndarray' object has no attribute 'isnan'

[michaelgondosari]

Hi, I'm looking to use this package for a predict-optimization project using ANFIS. When fitting the model as below, I got a numpy error in the sanfis/helpers.py file.

history = model.fit(train_data=[X_train, y_train], valid_data=[X_valid, y_valid], optimizer=optimizer, loss_function=loss_functions, epochs=200)

Perhaps line 263 of the helpers.py file needs to be modified from:
transformed_dataloder.dataset[1][transformed_dataloder.dataset[1].isnan()] = 0.0

into something like:
transformed_dataloader.dataset[1][np.isnan(transformed_dataloader.dataset[1])] = 0.0

as 'numpy.ndarray' object has no attribute 'isnan'.
Or can I fix this error without changing this section? Your help is very appreciated.
