attack.py cannot reshape array of size 12544 into shape (1,3,112,112)

[ziwenlu]

l try to use attack.py to prepare face attack. l followed you steps and when trying to use anchor_face .it shows me that File "attack.py", line 24, in prep
return np.transpose(im, [2, 0, 1]).reshape((1, 3, 112, 112)) * 2 - 1#.reshape( [1,3,120, 120])*2-1
ValueError: cannot reshape array of size 12544 into shape (1,3,112,112). Is there something l need to set

Have you solved it, please? I also had this issue, but I added the parameter'channel_axis=2' and 12544 became 50176.

[ziwenlu]

l don't solve it and do you have any ideas

[ziwenlu]

which line do you add the channel_axis=2?

rescale（channel_axis=2） nihao13548cun ***@***.***

l found my problem is the shape of image is(112,112,1)

However l use the image input is(600,600,3)

[ziwenlu]

and my tensorflow version is 1.14.0 with numpy 1.19.2

[cacoan]

you can try it   nihao13548cun ***@***.***

[ziwenlu]

so have you already manage to solve them?

[cacoan]

那么你已经设法解决它们了吗？

no

This problem is because your version of scikit-image is too high, when using the rescale function, it reads not an RGB image but a grayscale map, the solution is simple, either reduce the scikit-image version or replace the rescale function：
pip install scikit-image==0.14.2 -i https://mirrors.aliyun.com/pypi/simple/
