OSError: Model provided is schema version is not equal to supported version!

I have been running a tflite model on OpenMV H7 Plus, Firmware Version 4.3.1 for a while, since before July 2022. Today this blocking error popped up. I went back to earlier versions of my code and the error still appears where it never did before.

This is my code for loading the tf models.
self.tfmodel = tf.load(“TfModel_2022_07_31_1638.tflite”, load_to_fb=True)
self.tflabels = [line.rstrip(‘\n’) for line in open(“labels_tflite_pupil.txt”)]

Upgrading to Firmware 4.3.3 seems to have fixed this error.
