Getting a ValueError when I try to run the cnn_model function()

[abalamur]

for the Myquickdraw.ipynb code I am attempting to run the code but am getting the error

ValueError: Negative dimension size caused by subtracting 5 from 1 for '{{node conv2d/Conv2D}} = Conv2D[T=DT_FLOAT, data_format="NHWC", dilations=[1, 1, 1, 1], explicit_paddings=[], padding="VALID", strides=[1, 1, 1, 1], use_cudnn_on_gpu=true](conv2d_input, conv2d/Conv2D/ReadVariableOp)' with input shapes: [?,1,28,28], [5,5,28,30].

Is there. way I can fix this error? Thanks
