OverflowError: unsigned byte integer is greater than maximum

See original GitHub issue

When my dataset goes to 77000+ images, there is an error:

Traceback (most recent call last): File "convert-images-to-mnist-format.py", line 46, in <module> header.append(long('0x'+hexval[2:][2:],16)) OverflowError: unsigned byte integer is greater than maximum

Can anybody help me? I think it is because images too many, how to fix it?

Hey,

So my solution to this was to do the following.

` hexval = “{0:#0{1}x}”.format(len(FileList),10) # number of files in HEX

    # header for label array

    header = array('B')
    header.extend([0,0,8,1])
    header.append(int('0x'+hexval[2:][:2],16))
    header.append(int('0x'+hexval[4:][:2],16))
    header.append(int('0x'+hexval[6:][:2],16))
    header.append(int('0x'+hexval[8:][:2],16))

    
    data_label = header + data_label

    hexval = "{0:#0{1}x}".format(width,10) # width in HEX
    header.append(int('0x'+hexval[2:][:2],16))
    header.append(int('0x'+hexval[4:][:2],16))
    header.append(int('0x'+hexval[6:][:2],16))
    header.append(int('0x'+hexval[8:][:2],16))

    hexval = "{0:#0{1}x}".format(height,10) # height in HEX
    header.append(int('0x'+hexval[2:][:2],16))
    header.append(int('0x'+hexval[4:][:2],16))
    header.append(int('0x'+hexval[6:][:2],16))
    header.append(int('0x'+hexval[8:][:2],16))
