Conversion error

[Zumbalamambo]

Im getting the following error while conversion

File "cvs_to_numpy.py", line 71, in <module>
    image = data_to_image(row['pixels'])
  File "cvs_to_numpy.py", line 59, in data_to_image
    data_image = format_image(data_image)
  File "cvs_to_numpy.py", line 16, in format_image
    gray_border[((150 / 2) - (SIZE_FACE/2)):((150/2)+(SIZE_FACE/2)), ((150/2)-(SIZE_FACE/2)):((150/2)+(SIZE_FACE/2))] = image
TypeError: slice indices must be integers or None or have an __index__ method

you need to give integers to reach indices of gray_border.
use a int(float f) to make sure you get it right.

@AdrienPlayerium i didn't get it. can you tell how to solve this problem?

@mrinal18 In this code sample, he got a numpy array which contains pixel information, to pick the region of interest you got to pick a part of this matrix, that's what he tried above.
It's almost correct, the error is raised because the slices:
((150 / 2) - (SIZE_FACE/2)):((150/2)+(SIZE_FACE/2)):((150/2)-(SIZE_FACE/2)):((150/2)+(SIZE_FACE/2))
"select square of SIZE_FACE around (150/2,150/2) position"
is not well defined since the type of those numbers are floats... therefore a quick fix would be to cast to integers:
int((150 / 2) - (SIZE_FACE/2)):int((150/2)+(SIZE_FACE/2)):int((150/2)-(SIZE_FACE/2)):int((150/2)+(SIZE_FACE/2))

Got it. Thank you very much.
