ValueError: array is not broadcastable to correct shape!

[getengqing]

Hello, I got the error:

frontal_raw[ind_frontal, :] = cv2.remap(img, temp_proj2[0, :].astype('float32'), temp_proj2[1, :].astype('float32'), cv2.INTER_CUBIC)
ValueError: array is not broadcastable to correct shape

what's the error?How can i sovle?

Hi @getengqing,

Could you give more details about the error? How are you reading the image? Is it a RGB image? Are having this issue with one image in particular?

[getengqing]

I run your demo.py , I have no anyway change to your program. Then got the error!

[dougsouza]

That's odd. Which version of OpenCV are you using?

Hi, I've got the same error. OpenCV version is 2.4.8

@181066,

Could you give more details about the input image? It would be great if could share the image itself

[181066]

The input image is the one from your demo - test.jpg
I just run your code without changes. Well, initially I tried to use my image that was looking much more difficult for frontalization. It didn't find facial points and failed. Ok then I just decided to check your demo and got that error.

Thank you.

Try upgrading your numpy version

[181066]

I have the latest numpy 1.8.2 for ubuntu 14.04.

[dougsouza]

@181066, this is the not last version, I am using 1.10.4 on ubuntu 14.04, for example.

PS.: I am using the Anaconda python distribution.

[181066]

Thanks a lot. Works fine with Anaconda.

I also meet this problem and my numpy version is also 1.8.2.
I just use sudo pip install --upgrade numpy to get latest numpy 1.13.1, and this problem can be solved.
