chapter 10, is the for row_start in range(layer_0.shape[1]-kernel_rows) correct?

[DawnEve]

8x8 image with a 3x3 kernel, we get 6x6 output, which means 8-3+1=6.

when using
for row_start in range(layer_0.shape[1]-kernel_rows)
, it discards the last pixel in the row.

What do you think?

[DawnEve]

for i in range(6):
[i, i+3)
0 3
1 4
2 5
3 6
4 7
[5, 8) # this last slice shouldn't be neglected.

[chnwiki]

hidden_size = ((input_rows - kernel_rows+1) *
(input_cols - kernel_cols+1)) * num_kernels

for row_start in range(layer_0.shape[1]-kernel_rows+1):
for col_start in range(layer_0.shape[2] - kernel_cols+1):
sect = get_image_section(layer_0,
row_start,
row_start+kernel_rows,
col_start,
col_start+kernel_cols)
it works
