Hi, i am trying to install a python library on my raspberry pi 3 b device and i get this error after waiting a number of hours:

After executing pip3 install pithermalcam i get the above error after a number of hours of waiting for it to complete.

This is a problem installing opencv as the error says. There are instructions related to this instead on the instruction page, and if those don't work it's a problem to debug with open cv, not this library.

How do i install the opencv? the instructions are very vague on how to do so?

[tomshaffner]

You might search the instructions; there's actually a whole section discussing two different ways to install opencv. Ultimately though, opencv is just a dependency of this library; if installing it via pip is throwing errors, you'll be better off debugging that as a separate issue with opencv and then coming back to this library once it's fixed. If you're getting different behavior on your pi that's causing that to break, that suggests some other conflict or problem between it and your setup and that's not something this library can speak to. Hope that puts you on the right path to finding a solution.

[jonneymendoza]

the instructions are vague as 2nd step i dont understand:

Install remaining requirements using either: a. pip3 install the requirements.txt or b. pip3 install the requirements_without_opencv.txt
