Error in executing training and predictions

[dataplusplus-ai]

While executing this notebook https://github.com/mwdhont/SimCLRv1-keras-tensorflow/blob/master/2_model_SimCLR.ipynb in google colab, this code y_predict_test_before = SimCLR.predict(data_test) gives the following error.

ValueError: Failed to find data adapter that can handle input: <class 'DataGeneratorSimCLR.DataGeneratorSimCLR'>, <class 'NoneType'>
Converting data_test, data_train, data_val to numpy arrays does not help.

Similar error while executing this line also.
SimCLR.train(data_train, data_val, epochs = 5)

Try downgrade the Tensorflow and Keras version I think??
I also get the same result when try using the current version Tensorflow (v=2.9.2) and Keras (2.9.0) from google Colab.
But when I downgraded the tensorflow version into 2.1. and keras to 2.3.2. It works fine with me when I run the template code in Google Colab.
