Can you please help me with this, it took almost 2 days have tried 2 times of my time, but to no avail. I inspected the log deeply and searched online but without appreciable results. If you encounter compilation failures, you could try compiling with 1 core to eliminate race conditions by skipping the optional argument altogether. All the paths of interpreter, libraries, numpy, and packages path are like you described. Each step of the tutorial is important. But, how coud I enter into virtual environment from the next time onwards to use workon cv.
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.
This will resolve the stdlib. I have already manually copied the cv2. But it could be waste of time, due to my rookie status. Same issue, no idea how to solve it. Installed there the Ubuntu 18. Can you advise when you delete the build folder? Please tell me what to do. .
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. These two Python packages facilitate creating independent Python environments for your projects.
I just met one error before. In case of any queries, feel free to comment below and we will get back to you as soon as possible. We can check it by typing conda info opencv in command prompt and press enter of course, you'll see following - opencv 3. Hi Adrian, Thanks for this great post!

Bring the ball into the frame and move it around to see the red tracking trail! I tried just doing the last steps of symlinking to the other installation, but it seems not to work.
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. Any tips on how I can find and install these libraries so I can get started? I was wondering if the instructions for Ubuntu 18. If I am using python2 this is not working.
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.
