ValueError: Failed to find data adapter that can handle input: <class 'numpy.ndarray'>, <class 'pandas.core.frame.DataFrame'>

Question

In my code, my model is compiling fine but when I am using pd.get_dummies(pd.Series(test_labels)) to get the labels for the validation images, it gives me the following error.

File "train_model.py", line 43, in <module>
    pd.get_dummies(pd.Series(test_labels))])
  File "C:\Users\ariji\AppData\Local\Programs\Python\Python37\lib\site-packages\tensorflow_core\python\keras\engine\training.py", line 728, in fit
    use_multiprocessing=use_multiprocessing)
  File "C:\Users\ariji\AppData\Local\Programs\Python\Python37\lib\site-packages\tensorflow_core\python\keras\engine\training_v2.py", line 224, in fit
    distribution_strategy=strategy)
  File "C:\Users\ariji\AppData\Local\Programs\Python\Python37\lib\site-packages\tensorflow_core\python\keras\engine\training_v2.py", line 497, in _process_training_inputs
    adapter_cls = data_adapter.select_data_adapter(x, y)
  File "C:\Users\ariji\AppData\Local\Programs\Python\Python37\lib\site-packages\tensorflow_core\python\keras\engine\data_adapter.py", line 653, in select_data_adapter
    _type_name(x), _type_name(y)))
ValueError: Failed to find data adapter that can handle input: <class 'numpy.ndarray'>, <class 'pandas.core.frame.DataFrame'>

What seems to be the issue? My model is a simple tensorflow sequential model.

That is because pd.get_dummies gives a pd.DataFrame. You need to convert that to numpy.ndarray type.

Try

pd.get_dummeis(pd.Series(test_labels)).to_numpy()

Thanks, it worked. Somehow I got this problem when I was running an old code of mine with tf2. It used to work fine with the old tensorflow
