TypeError: only integer scalar arrays can be converted to a scalar index

[Charuwaka]

we have a python script which work fine in PC , but we run same script in android app we are getting above error. "TypeError: only integer scalar arrays can be converted to a scalar index" and its exactly failing at this line cv2.circle(mask, (cx, cy), radius -68, (255, 255, 255), thickness=-1)

I'm not familiar with this error, but there are many results for it on Google. Please have a look at them.

If you still can't work out the solution, please post the full stack trace.

gone through almost like 20 forums question couldn't find a solution , problem is this is working perfectly in windows , but failing while running through. chacopy

[mhsmith]

Post the full stack trace please.

I can't find any examples of this error being produced by cv2.circle. Are you absolutely certain that circle_detect.py line 141 is the line you posted? For example, is it possible that you edited the source code since the last time you rebuilt the app?

If you're sure this is the line causing the error, please add the following lines before it, and post the output they produce in the Logcat:

print(mask.shape, mask.dtype)
print(cx, cy, radius)

It might also be useful if you posted some of the other lines leading up to it.

I/python.stdout: (1603, 2180) I/python.stdout:
I/python.stdout: uint8 I/python.stdout:
I/python.stdout: [979] I/python.stdout:
I/python.stdout: [950] I/python.stdout:
I/python.stdout: [450] I/python.stdout:

[mhsmith]

I think cx, cy and radius should be numbers, not lists.

[Charuwaka]

you mean [979] [950] ?

[mhsmith]

Yes, and [450]. They're printed with square brackets, so I think they must be lists. Check your code to see how this happened.

sure thanks!
