Running ERROR with my own video

[YibinWu]

hello，i am using the program to process my own videos which are already resize to 1280*720,and error below is appearing.
`
File "C:\Users\10401\AppData\Local\conda\conda\envs\TensorFlow\lib\site-packages\numpy\core_methods.py", line 29, in _amin
return umr_minimum(a, axis, None, out, keepdims)

ValueError: zero-size array to reduction operation minimum which has no identity`
i am not familiar with python.So why it appears and how can i solve the problem?

Same here. When I was processing the challenge_video, I got the same error with you. Did you solve it?

[YibinWu]

No,I did not.If you know how to solve it please share it here.thanks!

Did you already run this code successfully on the original video before making changes?

Also, what was the full error message? Error messages are usually at least 10 lines long, and the rest of the message is helpful for determining what went wrong.

Hi,

I tried using the original video and the code works fine. But like the others above when I try my own video the program crashes with the following error:

If the input size is the problem, I checked the sample video size 1280x720. That's the same size I'm suing for my own video.

FYI: I'm not using a GPU
