I have used homebrew to install OpenCV, but I cannot use it, when I import OpenCV in Python, I meet this error:
ImportError: No module named cv2; op
system:macos10.12.6
opencv 3.3.0_2
python 2.7.13

I'm trying to use matplotlib on spyder 3.3.6 but I'm having trouble importing it in the first place, is there some way to install matplotlib beforehand? I don't have a very specific question, I guess I'm just requesting someone to help me with this. I'm pretty new to using python
import matplotlib.pyplot as plt
and it returns " ImportError: No module named matplotlib.pyplot "
when I run
pip install matplotlib
I get
pip install matplotlib
^
SyntaxError: invalid syntax
l'm under python2.7 l can't import data_io l got this error :
ImportError: No module named data_io
Here is my code
import data_io
reload(data_io)
data = data_io.read_as_df(basename)
Have you run the command?
pip install dataIO
If so are you sure it is install in the right directory? Please provide more details on your pathenv.
I try to install OpenCV but it doesn't work, I get import error:
from conda.cli.main import main
ImportError: No module named conda.cli.main
I'm trying to install Scikit and run a python file that only has:
import sklearn
To check if Scikit works. This is the error I get:
Traceback (most recent call last):
File "hello-world.py", line 1, in
import sklearn
File "/Library/Python/2.7/site-packages/sklearn/init.py", line 57, in
from .base import clone
File "/Library/Python/2.7/site-packages/sklearn/base.py", line 9, in
from scipy import sparse
ImportError: No module named scipy
I have been at this for hours now. My python version is Python 2.7.11
which -a python
gives me this:
/usr/local/bin/python
/usr/bin/python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
/Users/Iliad/anaconda/bin/python
I had had Python 3.5 Installed before, but downloaded Anaconda for 2.7, but can't make sure it is set to work with that version.
Thanks!
I will start with
python --version
Just to be sure
and then in python repl. Use this
import site
site.getsitepackages()
This would give you something like :
['/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages']
Check in all the dist-packages for scipy. My guess is that it is not there.
If you have any other "dist-packages" type of folder then you should add that to your PYTHONPATH.
I've correctly build OpenCV in OS X and I can use it with C++,
however, when I try to load the cv2 module from Python, I get this error:
import cv2
Traceback (most recent call last):
File "", line 1, in
ImportError: dlopen(/usr/local/lib/python2.7/site-packages/cv2.so, 2): Symbol not found: _ZN2cv11FileStorageC1ERKSsiS2

I have the same issue both with python and opencv installed from macports and when compiling OpenCV by my self. I have tried to use Python 2.7.5 and 2.7.6 and opencv 2.4.5 and 2.4.6.1
