I want my pyrealsense2 to be installed in python3 iv'e been using this instruction by @MartyG-RealSense https://github.com/IntelRealSense/librealsense/issues/6964#issuecomment-665650908 I run the command: cmake ../ -DFORCE_RSUSB_BACKEND=ON -DBUILD_PYTHON_BINDINGS:bool=true -DPYTHON_EXECUTABLE=/usr/bin/python3 -DCMAKE_BUILD_TYPE=release -DBUILD_EXAMPLES=true -DBUILD_GRAPHICAL_EXAMPLES=true -DBUILD_WITH_CUDA:bool=true But still when I run sudo make install I get: -- Up-to-date: /usr/lib/python2.7/dist-packages/pyrealsense2/pybackend2.cpython-38-aarch64-linux-gnu.so.2.50.0 Why is not installing in python3 dist-packages?

Hi @eladpar I recommend using the Jetson installation guide at https://github.com/IntelRealSense/librealsense/issues/6964#issuecomment-707501049 which is further down the page that you linked to.

Hi @eladpar I recommend using the Jetson installation guide at #6964 (comment) which is further down the page that you linked to.

Sorry my link was wrong I did use the one you sent

/pybackend2.cpython-38-aarch64-linux-gnu.so is a filename that would be created when building the pyrealsense2 wrapper if Python 3.8 is installed on your computer.

Have you performed steps 7 and 8 - setting the PYTHONPATH and sourcing the bashrc file?

But i'm in step 6 ... your'e saying it did detect im using python3.8 but still put the artifacts in the wrong folder

steps 7 and 8 are not relevant because the folder is not located in /usr/local/lib/python3.8

In the guide there is a typing mistake where there should not be a space between '-' and 'DPYTHON' in:

- DPYTHON_EXECUTABLE=/usr/bin/python3.6

Did you close up the space between - and DPYTHON when using the CMake build instruction? And did you modify the instruction to say python3.8 instead of python3.6 if 3.8 is the Python version that is installed on your computer?

You can confirm which Python 3 version you have with the command which python3

I changed it to be '-DPYTHON_EXECUTABLE=/usr/bin/python3' and I checked that my python3 executable is '/usr/bin/python3'

It may be worth starting the installation process again and when you get to step 6, use the CMake command below instead whilst in the 'build' folder to uninstall the currently installed SDK and then begin a new installation of the SDK and pyrealsense2 wrapper.

sudo make uninstall && make clean && make -j4 && sudo make install

If you are not certain which Python 3 version number you have got installed on your computer then use:

-DPYTHON_EXECUTABLE=/usr/bin/python3
