At run time model.fit with the following input parameters:

model.fit(X, y, batch_size=32, epochs=20, validation_split=0.2 ,callbacks=[tensorboard])

the following error is encountered:

`validation_split`

is only supported for Tensors or NumPy arrays, found following types in the input: [<class ‘int’>, <class ‘int’>, <class ‘int’>, <class ‘int’>, <class ‘int’>, <class ‘int’>, <class ‘int’>, <class ‘int’>, <class ‘int’>, <class ‘int’>, <class ‘int’>, <class ‘int’>, <class ‘int’>, …

the tensorflow-gpu version is 2.7.1

numpy version is 1.23.2

Could this be from the Nampy version?
