Hello @"franva"#p1659 , I assume this happened because there were no prebuilt wheels for RPI. Version **2.9.0.0 and newer** have prebuilt wheels for RPI. Could you update the repo to latest version and try again? Thanks, Erik

Hi @"erik"#p1667 thanks for your help. I assume that you meant the version 2.9.0.0 for **depthai** right? (because I saw the version for depthai is 2.8.0.0) I went back and updated the project(depthai) and saw a few updates: ``` From https://github.com/luxonis/depthai adbc84f..cf6fbc7 main -> origin/main Updating adbc84f..cf6fbc7 Fast-forward depthai_demo.py | 2 +- depthai_helpers/arg_manager.py | 2 +- depthai_helpers/managers.py | 2 +- 3 files changed, 3 insertions(+), 3 deletions(-) ``` But I didn't see any updates happened in requirements.txt, it's still asking for **2.8.0.0** for depthai. And I then went to Depthai github and I am not able to find the version 2.9.0.0 [URL=https://i.imgur.com/Ra1CAhy.png][IMG]https://i.imgur.com/Ra1CAhy.png[/IMG][/URL] So could you please confirm that version 2.9.0.0 is for?? And more details are appreciated. Many thanks, Winston

hi @"erik"#p1667 I think I found the [version 2.9.0.0 here](https://pypi.org/project/depthai/) So did you mean that after I installed the version 2.9 I can remove many dependencies in `requirements.txt` and make it look like: ``` requests==2.24.0 argcomplete==1.12.1 blobconverter==0.0.10 # --extra-index-url https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/ # depthai==2.5.0.0.dev+568cf1c566056eac5a039ebb9a1fa74436c495b5 depthai==2.9.0.0 pytube==10.8.5 ``` Am I correct?

Hi @"erik"#p1667 I have successfully installed Depthai 2.9.0.0 and then I commented out the `opencv-python` and `opencv-contrib-python` in the `requirements.txt` and I ran `python3 install_requirements.py` It ran successfully. **Then I tried to install `opencv-python` (because the program still asks for cv2) by running `pip install opencv-python`, then I got the huge error again:** ``` std::vector::iterator’ {aka ‘__gnu_cxx::__normal_iterator’} changed in GCC 7.1 vector:: ^~~~~~~~~~~~~~~~~~~ In file included from /usr/include/c++/8/vector:64, from /tmp/pip-install-es1i8wl_/opencv-python_8b24e6464d3a4a5a958de46d09bbbb93/opencv/modules/stitching/src/precomp.hpp:48, from /tmp/pip-install-es1i8wl_/opencv-python_8b24e6464d3a4a5a958de46d09bbbb93/opencv/modules/stitching/src/motion_estimators.cpp:43: /usr/include/c++/8/bits/stl_vector.h: In function ‘std::vector cv::detail::leaveBiggestComponent(std::vector&, std::vector&, float)’: /usr/include/c++/8/bits/stl_vector.h:1085:4: note: parameter passing for argument of type ‘__gnu_cxx::__normal_iterator’ changed in GCC 7.1 _M_realloc_insert(end(), __x); ^~~~~~~~~~~~~~~~~ [ 85%] Building CXX object modules/stitching/CMakeFiles/opencv_stitching.dir/src/seam_finders.cpp.o [ 86%] Building CXX object modules/stitching/CMakeFiles/opencv_stitching.dir/src/stitcher.cpp.o In file included from /usr/include/c++/8/bits/stl_algo.h:61, from /usr/include/c++/8/algorithm:62, from /tmp/pip-install-es1i8wl_/opencv-python_8b24e6464d3a4a5a958de46d09bbbb93/opencv/modules/stitching/src/precomp.hpp:49, from /tmp/pip-install-es1i8wl_/opencv-python_8b24e6464d3a4a5a958de46d09bbbb93/opencv/modules/stitching/src/stitcher.cpp:43: /usr/include/c++/8/bits/stl_heap.h: In function ‘void std::__adjust_heap(_RandomAccessIterator, _Distance, _Distance, _Tp, _Compare) [with _RandomAccessIterator = __gnu_cxx::__normal_iterator; _Distance = int; _Tp = double; _Compare = __gnu_cxx::__ops::_Iter_less_iter]’: /usr/include/c++/8/bits/stl_heap.h:214:5: note: parameter passing for argument of type ‘__gnu_cxx::__normal_iterator’ changed in GCC 7.1 __adjust_heap(_RandomAccessIterator __first, _Distance __holeIndex, ^~~~~~~~~~~~~ In file included from /usr/include/c++/8/algorithm:62, from /tmp/pip-install-es1i8wl_/opencv-python_8b24e6464d3a4a5a958de46d09bbbb93/opencv/modules/stitching/src/precomp.hpp:49, from /tmp/pip-install-es1i8wl_/opencv-python_8b24e6464d3a4a5a958de46d09bbbb93/opencv/modules/stitching/src/stitcher.cpp:43: /usr/include/c++/8/bits/stl_algo.h: In function ‘void std::__insertion_sort(_RandomAccessIterator, _RandomAccessIterator, _Compare) [with _RandomAccessIterator = __gnu_cxx::__normal_iterator; _Compare = __gnu_cxx::__ops::_Iter_less_iter]’: /usr/include/c++/8/bits/stl_algo.h:1840:5: note: parameter passing for argument of type ‘__gnu_cxx::__normal_iterator’ changed in GCC 7.1 __insertion_sort(_RandomAccessIterator __first, ^~~~~~~~~~~~~~~~ /usr/include/c++/8/bits/stl_algo.h:1840:5: note: parameter passing for argument of type ‘__gnu_cxx::__normal_iterator’ changed in GCC 7.1 /usr/include/c++/8/bits/stl_algo.h:1840:5: note: parameter passing for argument of type ‘__gnu_cxx::__normal_iterator’ changed in GCC 7.1 /usr/include/c++/8/bits/stl_algo.h: In function ‘void std::__introsort_loop(_RandomAccessIterator, _RandomAccessIterator, _Size, _Compare) [with _RandomAccessIterator = __gnu_cxx::__normal_iterator; _Size = int; _Compare = __gnu_cxx::__ops::_Iter_less_iter]’: /usr/include/c++/8/bits/stl_algo.h:1940:5: note: parameter passing for argument of type ‘__gnu_cxx::__normal_iterator’ changed in GCC 7.1 __introsort_loop(_RandomAccessIterator __first, ^~~~~~~~~~~~~~~~ /usr/include/c++/8/bits/stl_algo.h:1940:5: note: parameter passing for argument of type ‘__gnu_cxx::__normal_iterator’ changed in GCC 7.1 /usr/include/c++/8/bits/stl_algo.h:1954:25: note: parameter passing for argument of type ‘__gnu_cxx::__normal_iterator’ changed in GCC 7.1 std::__introsort_loop(__cut, __last, __depth_limit, __comp); ~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from /usr/include/c++/8/vector:69, from /tmp/pip-install-es1i8wl_/opencv-python_8b24e6464d3a4a5a958de46d09bbbb93/opencv/modules/stitching/src/precomp.hpp:48, from /tmp/pip-install-es1i8wl_/opencv-python_8b24e6464d3a4a5a958de46d09bbbb93/opencv/modules/stitching/src/stitcher.cpp:43: /usr/include/c++/8/bits/vector.tcc: In member function ‘void std::vector::_M_realloc_insert(std::vector::iterator, _Args&& ...)

Having issue for installation on RPi 4 B 4GB

erik

Hello franva, sorry for not specifying this beforehand; yes, I meant depthai library version 2.9.0.0. I wasn't aware that we haven't updated the depthai repo (setting depthai lib version in requirements.txt), sorry for trouble. Yes, you are correct about changing the version in requirements.

erik

Hello franva, so this means that opencv doesn't have prebuilt wheels for your host. I assume you are using RaspberryPi, so here are the supported python versions for the opencv:
https://www.piwheels.org/project/opencv-python/
I would suggest using python 3.7 or 3.9 (they come preinstalled with the buster/bullseye version of the RaspberryPi OS), so installing the library will just download the prebuilt library instead of trying (& failing) on building it. I hope this makes sense!
Thanks, Erik

franva

erik brilliant_! There is the wheel already ! haha thanks a lot_!

For the opencv-contrib-python I found it here
However, it does not have the same version 4.5.3.56 as for opencv-python.

If I installed the older version opencv-contrib-python, will it cause issues?(I imagine they won't be compatible which is a big issue)
Why do I still need opencv-contrib-python even after I installed opencv-python?

Once again, thanks for your help.

Cheers,

Winston

erik

Hello franva, I actually think you could just use that version - the opencv-contrib only adds some extra functionalities, and I believe we use only the basic functions, which should be available in the mentioned version.
Thanks, Erik

franva

thanks erik so "that version" means the version for opencv-python, right?

And if I understood you correctly, I won't need the opencv-contrib-python right?
It would be a great relief if I didn't need to install one more hard-to-install package haha.

Thanks
Winston

erik

My bad franva for not being clear; I meant that you could try using python version 3.7/3.9 and opencv-python and opencv-conrib-python version 4.4.0.46 (as both of these packages has prebuilt wheels).

On this note, I have opened a feature request to fix this mess so you will be able to install requirements on RPI without having to deal with all these version issues.
Thanks, Erik

franva

Morning erik Now I understood, I can install

Depthai 2.9.0.0
opencv-python 4.4.0.46
opencv-conrib-python 4.4.0.46

I have checked the Github code for DepthAI and still cannot find the version 2.9.0.0. So I hope the version 2.9.0.0 of DepthAI(DAI) will be compatible with the 4.4.0.46 of both opencv-conrib-python(OCP) and opencv-python(OP).

erik

Good morning franva, depthai version 2.9 and newer actually have prebuilt pi wheels - so running python3.7 -mpip install depthai==2.9.0.0 should install prebuilt library to your RPI.
Thanks, Erik

franva

thanks erik for clarifying the installation. So I just need to install the depthai 2.9.0.0 and this lib will contain OCP and OP.

Okay, so after I installed it and a couple of other dependencies(including setup the USB rules) and I ran:

$ python3 depthai_demo.py -cnn deeplabv3p_person

So this is the error I got. Could you please help?
Btw, my python3 is 3.7.3

Many thanks,

erik

Hello franva , in the new 2.9 version there is no longer dai.ColorCamera but dai.node.ColorCamera. We will update depthai_demo today to the new 2.9 version, sorry for the issues.
Thanks, Erik

franva

hi erik thanks for your timely update.
Excitingly, after I fixed a few other places, it finally works now_!

I have created a PR for this.
https://github.com/luxonis/depthai/pull/446

I hope to contribute to this great project 🙂

Cheers,

Winston

erik

franva Thanks again for the PR!
