OpenCV installation issue

[NOOBscripts]

Hi guys I have downloaded python 3.6 install it:works fine . After I have install Numpy, Matplotlib. Also I have downloaded opencv.whl.
I am trying to install it by

pip install opencv_python-3.3.0-cp35-cp35m-win_amd64.whl

but I am always getting following error.

Fatal error in launcher: Unable to create process using '"'

After this I tried to download opencv-3.3.0-vc14.exe. I did everything by instruction. Copy cv2 file in site-package directory but everything unsuccessful.
Somebody help me. How Can I install openCV in python
P.S it already works for java.

Hi,

Have you tried installing it/using it  as OpenCV rather then opencv?

Please clarify your question I don't understand what you mean.

Hi,

Python can be case sensitive.

So if you install a package/library as DUMMY then you will need to import it into your script as DUMMY i.e. the libraries can be case sensitive.

If however the library is called Dummy then you will need to refer to it as Dummy and *not* DUMMY or dummy.

In your post you referred to the library as OpenCV but in your pip command it was opencv_python.

So you *could* have two seperate libraries, one called DUMMY_ONE and one called Dummy_One. These would be treated as two different libraries.

Does this make more sense?

Hi,

Further to earlier reply....

Have you seen snippsats link to OpenCV help this came from this thread  posted on the 15th Aug 2017. It is not a package that I use.... But hopefully may help.

Good Luck

Hi guys I have downloaded python 3.6 install it:works fine

But you try installing openCV wheel for Python 3.5.
cp35 means that's it for Python 3.5,win_amd64 means that Python version is 64-bit.

Here a demo om me using it,i have Python 3.6 which is 32-bit.
I use virtual environment,but it's the same way to install to OS version of Python.

# Check pip
(py_in) E:\1\py_in\dist
λ pip -V
pip 9.0.1 from e:\1\py_in\lib\site-packages (python 3.6)

# Check if Python is 32 or 64 bit
(py_in) E:\1\py_in\dist
λ python
Python 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 17:54:52) [MSC v.1900 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()

# Install with correct wheel for 3.6 and 32-bit.
(py_in) E:\1\py_in
λ pip install opencv_contrib_python-3.3.0.9-cp36-cp36m-win32.whl

Ok guys thanks for your response. I eventually have installed opencv module from
Python official site
I couldn't install it because my python was 32 bit and I try to install 64 bit.(Dummy fault in know )
After installation when i try to import library I get this.

C:\>python -m pip install opencv_contrib_python-3.3.0.9-cp36-cp36m-win32.whl
Processing c:\opencv_contrib_python-3.3.0.9-cp36-cp36m-win32.whl

>>> import cv2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

Any idea how to fix it?

ImportError: DLL load failed: %1 is not a valid Win32 application.

This means that there problem with 32-64 bit,for you it's mean that's 64-bit when it should be 32-bit.
You most try to uninstall the wrong version you did installed first.

Requirement already satisfied: numpy>=1.11.3

Here you see that is already installed,this can be 64-bit version of numpy.
pip uninstall wheel-version

Guys everything is done. I just remove python 3.6 and install 2.7 it with libs, now everything works correctly.
Thanks for reply guys.

Okay good that work,but you should really use 3.6 not 2.7
