Visualizing Model Predictions on Test Dataset with Matplotlib Histogram

This code block leverages the variable 'INFER_TEST' to determine if the code is currently performing inference on the test dataset. If so, it generates and displays a histogram of the model's predictions on the test dataset using the Matplotlib library. The histogram is constructed with 100 bins and titled 'Test Predictions'. Finally, the matplotlib 'show()' function displays the histogram.
