I’m trying to install Olympe onto a Linux 18.04 LTS distribution, and during the olympe-dependencies installation, I run into the error “Could not find a version that satisfies the requirement opencv-python” “No matching distribution found for opencv-python”. After manually installing opencv-python, the error does not seem to be resolved.

Hello,
In the Olympe python environment, what is the output of the pip freeze command ?
$ source shell
(olympe-python3) $ pip freeze
Could you please share the complete log of execution of the postinst script. Thanks
aware@aware-jetson:~/code/parrot-groundsdk$ source ./products/olympe/linux/env/shell (olympe-python3) aware@aware-jetson:~/code/parrot-groundsdk$ pip freeze
I get no output for `pip freeze’ in the Olympe Python environment.

Hi,
The Nvidia Jetson TX2 has an ARM CPU (aarch64) and it seems that the opencv-python package is not compatible with the aarch64 architecture.
Could you try replacing opencv-python by opencv-python-aarch64 in ./package/olympe/requirements.txt (opencv-python-aarch64 seems to be provided by the same maintainer) and then retry the postinst script. Thanks
