ALL, New to Python and OpenCV - trying to follow the tutorials. Created Python 2.7.11 environments (32b & 64b) with Miniconda Included numpy 1.10.4 & matplotlib 1.5.1 Added opencv (3.1.0) cv2.pyd to the sit-packages from opencv build\python\2.7\[x64|x86]\cv2.pyd Entered environment and did the following: (Note: this is the x64 output, x86 was identical.) ***** [OCV] C:\Users\XXXXXX>python Python 2.7.11 |Continuum Analytics, Inc.| (default, Jan 29 2016, 14:26:21) [MSC v.1500 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. Anaconda is brought to you by Continuum Analytics. Please check out: http://continuum.io/thanks and https://anaconda.org>>> import numpy as nb>>> import cv2>>> import os>>> os.chdir('C:\Users\XXXXXX\Pictures\Invoices')>>> os.getcwd() 'C:\\Users\\XXXXXX\\Pictures\\Invoices'>>> img = cv2.imread('invoice.jpg',0)>>> print img [[255 255 255 ..., 255 255 255] [255 255 255 ..., 255 255 255] [255 255 255 ..., 255 255 255] ..., [255 255 255 ..., 255 255 255] [255 255 255 ..., 255 255 255] [255 255 255 ..., 255 255 255]]>>> cv2.__version__ '3.1.0'>>> exit() [OCV] C:\Users\XXXXXX>conda list # packages in environment at C:\Miniconda2\envs\OCV: # cycler 0.9.0 py27_0 jpeg 8d vc9_0 [vc9] libpng 1.6.17 vc9_1 [vc9] libtiff 4.0.6 vc9_1 [vc9] matplotlib 1.5.1 np110py27_0 mkl 11.3.1 0 msvc_runtime 1.0.1 vc9_0 [vc9] numpy 1.10.4 py27_0 pip 8.0.2 py27_0 pyparsing 2.0.3 py27_0 pyqt 4.11.4 py27_5 python 2.7.11 2 python-dateutil 2.4.2 py27_0 pytz 2015.7 py27_0 qt 4.8.7 vc9_6 [vc9] setuptools 19.6.2 py27_0 sip 4.16.9 py27_2 six 1.10.0 py27_0 tk 8.5.18 vc9_0 [vc9] wheel 0.29.0 py27_0 zlib 1.2.8 vc9_2 [vc9] ***** Now - I'm pretty sure that the img object should have had something other than black/white in the array - How would I troubleshoot/Debug this? Is there an incompatibility with OpenCV and the stack(s) created? Thanks - Tony
