install cv2 python ubuntu

I have no idea what I am doing. As with Kara my Python 2. If you are going to get into a lot of trouble if you start apt-get installing the Python packages. I installed opencv through this post completely. Y am using it with no problem, after installing the 3. I know my confusion stems from a lack of understanding of how virtual environments work. When I open a new terminal, logout, or reboot my Ubuntu system, I cannot execute the mkvirtualenv or workon commands.

Besides, most of the programmers and project manager at least my experiences told me do not like programming at all.

I am only stuck on the last bit, and I think it is because I have previously installed Anaconda on my computer. I would recommend using nano , vim , or emacs. A: If the import fails on Windows, make sure you have installed. Python virtual environments are a best practice and I suggest you use them whenever possible. Python 3 is what I suggest for development these days, but I do understand the need for Python 2. It was my mistake, I was trying to follow the steps for Ubuntu but I needed install in raspberry with Raspbian stretch.

So when I eventually want to open the cv2 file, it cannot be found. I try to dig around as long as I can before posting stupid comments. Thanks again for your time and support with these tutorials. The contrib repo contains extra modules and functions which we frequently use here on the PyImageSearch blog. I tried to remove the build folder and recompile using simply make, as suggested, but the same error continued stopping me, showing problems about potobuf packages. But you may need to isntall Microsoft Visual C++ redistributable package accoriding to your python package. Any remedy to this problem? Start by downloading the next image: Save it as clouds.

For many scientific developers, the move from Python 2. And for many of us, that was okay. I am almost through, gone through all the steps, but when I want to open cv2 in python it does not find the module. Then copy the resulting cv2.

Have you considered to add such feature during the install process? You could verify this by running ccmake. You should see something like in the next figure: If you want to learn more about Python and Matplotlib, I recommend reading by Eric Matthes. I used apt-get to install opencv-python. I just noticed however, that I need some additional libs to the ones you recommended. See reason 2 from the previous question. Update 2018-12-20: The following paths have been updated.

There are some notes on how to install Numpy for 3. I have Ubuntu hosted in virtual box. If you can help me with this or hint what's wrong that would really help me. Thanks for the amazing tutorial.

So my suggestion to you is to download Anaconda. I am using conda environment, so first i activated the environment. One thing should keep in mind that , the supported package of numpy an opencv for specific version of python is important to match. Note In this case, we are using 32-bit binaries of Python packages. I have been trying to follow the instructions but the cv2 library was not installed.
