Description

While following the textbook and the steps on Github on the cell counting task, when I run

model.restore()

it throws the following error:

INFO:tensorflow:Restoring parameters from model/model-7700
and
NotFoundError: Restoring from checkpoint failed. This is most likely due to a Variable name or other graph key that is missing from the checkpoint. Please ensure that you have not altered the graph expected based on the checkpoint. Original error:

2 root error(s) found.
(0) Not found: Key Conv2D_3/conv2d_4/bias not found in checkpoint
[[node save_3/RestoreV2 (defined at /tensorflow-1.15.2/python3.6/tensorflow_core/python/framework/ops.py:1748) ]]
