Q&A
openCV3のインストールについて質問させていただきます。
環境はMac OSX10.10.5、python3.4.3が使える状況です。
一応、おそらく無事インストールできている雰囲気なのですが、ターミナルより試すと
bash
1python3 2Python 3.4.3 (default, Aug 11 2015, 08:57:25) 3[GCC 4.2.1 Compatible Apple LLVM 6.1.0 (clang-602.0.53)] on darwin 4Type "help", "copyright", "credits" or "license" for more information. 5>>> import cv2 6Traceback (most recent call last): 7 File "<stdin>", line 1, in <module> 8ImportError: No module named 'cv2'
となってしまいます。
インストールする処理の過程などもいろいろ調べてみたのですが、原因がイマイチわからないので、どなたか教えていただけませんでしょうか。
ちなみにターミナルで行った処理とそのときのエラーです。
bash
