I then recreated the python2 virtual environment and finished the steps, but I did the make without the -j4 and went to bed. Do you know how to solve this problem? Perhaps some guidance on choosing python3 vs. Please take a look at it. Cheers, Leon Hi Leon — that is the intended behavior of Python virtual environments. Since you deviated slightly from the tutorial, I would suggest doing two things as a sanity check: 1. Do I have to go through all of the steps above, or are their shortcuts that are faster and simpler? You can either use Python 2.

As for wearing out the flash card, you can try running fstrim on the card every week to make sure the maximum amount of blocks are available for wear leveling. It takes around 10 min on a Core i5-3320M. Thanks One more thing, if I go to check the links setup in Step 5 they are still valid and showing appropriately in the virtualenvs directory as well as when using the readlink command. As for installing matplotlib or any other package that is pip-installable , you just need to enter the cv virtual environment first and then install: thank you for ur video:. Initially I created the cv env with python3 as shown, then I created another cvpy2. To upgrade your Raspberry Pi 3 to Raspbian Stretch, you may and follow these or which is recommended for beginners.

Because I want to install opencv and python and the disk space is not enough. You could easily install it via pip: For Python3: apt-get install python3-pip python3-dev apt-get install libqtgui4 apt-get install libqt4-test pip3 install opencv-python For Python2: apt-get install python-pip python-dev apt-get install libqtgui4 apt-get install libqt4-test pip2 install opencv-python. Unfortunately, this error is extremely hard to diagnose, mainly because there are multiple issues that could be causing the problem. I tried to manually install cmake using wget from the mirror on the cmake website and still the same error comes up. Make sure cmake finishes without errors.

You can create as many Python virtual environments as you want on a single machine. Thank you for this tutorial. First, you should read my reply to Rob James above. I would greatly appreciate your help. Do you have any suggestion? It will probably take forever but will it do it? Do I need to recompile opencv in the new virtual environment? If you do: Hello Adrian, Thanks for the great work. I spent days trying get opencv working on my raspi B+.

Make sure that the sym-link path to the cv2. I presume this is likely because of the 64-bit architecture of the Pi 3. Beginners get in a tedious compiling process without ever knowing there is an already compiled package. Is this anything I should worry about, and if so, is there an easy way to fix the issue, or would I need to start from the beginning and reinstall opencv? I want to ask something. I get unable to locate package sudo apt-get install libopencv-dev python-opencv Reading package lists. I was also able to run your Pokémon color detector game! Is the same situation likely to be the case when I move onto the later Chapters and Case Studies which use mahotas, scikit-learn and scikit-image? These generators create a bridge between C++ and Python which enables users to call C++ functions from Python.

However, if your make command errors out, I would suggest starting the compilation over again and only using one core: - rw - r -- r -- 1 root staff 1675144 Oct 17 15 : 25 cv2. Thanks in advance Sigi Hi, I tried with rpi2 — jessi — python2. You can verify this using the ls command: - rw - r -- r -- 1 root staff 1895772 Mar 20 20 : 00 cv2. This will also solve the problem. Make sure you have ran all of the previous apt-get commands to pull in the required prerequisites. I religiously followed all the steps until Step 5. Hi Adrian, I have also run into this.

I really think you should try to do some research in finding some possible solutions for this possible. When I install raspian on it, the folder manager of rasperry pi shows the free space about 700mb. This is made possible by the bindings generators. I was able to successfully unzip opencv. I hope the project is just that because learning it is another huge effort, certainly. Using virtualenv and virtualenvwrapper allows you to create isolated Python environments, separate from your system install of Python.

It indeed fixed the problem, sorry for taking your time for moderating! If I try and execute any python in the virtual environment I had previously, python import fails.

Dear Adrian, In step 5 , I am sure I am in the cv virtual env. I just upgraded to Jessie, and something broke on the previously stable virtual environment I setup using your instructions for Python 2. I will be visiting your kickstarter and getting that book! Best regards, Damon Hi Adrian can you please guide me through this? It works like a charm. Thanks very, very much for all the time and effort you have put into this. Do you have an idea why this might be happening? If I want to upgrade, I have to commit fully and re-install from scratch. Readers have been big fans of this post on.
