Root Cause

Batch size mismatch between predictions and labels.

generic

Workarounds

  1. 90% success Ensure labels shape matches model output: check dataset pipeline
  2. 88% success Use model.compile with from_logits=True and matching shapes

Dead Ends

Common approaches that don't work:

  1. Reshape labels arbitrarily 85% fail

    Creates wrong label-prediction alignment

  2. Change loss function to avoid shape check 82% fail

    Computes wrong loss
