Hi @Henery1

This looks like a mismatch between torchvision versions.
It was likely caused by an issue in installation instructions.
I'll look into this!

@Henery1

What version of torch and torchvision are you using?
You can check that by inspecting the output of the following commands:

pip3 show torchvision
pip3 show torch

Hi @tomek-l ! First of all Thanks you very much for your kindly respond. I used for thermal-view with purethermal-2 break out board and FLIR Lepton 3.5 and pi-camera v-2.1 for RGB . Please Look at the torch and torchvision below:

Hi @tomek-l
I got that kind of error. Please guide me to get RGB and IR frame display.

Hi @Henery1 ,
I'm glad you were able push it forward. Te second error is likely related to the gstreamer pipeline for RGB camera not having set up successfully.

1. See if you can display camera 0 on the screen:

gst-launch-1.0 nvarguscamerasrc sensor_id=0 ! 'video/x-raw(memory:NVMM),width=3264, height=2464, framerate=21/1, format=NV12' ! nvvidconv flip-method=2 ! 'video/x-raw,width=960, height=720' ! nvvidconv ! nvegltransform ! nveglglessink -e

(or camera 1):

gst-launch-1.0 nvarguscamerasrc sensor_id=1 ! 'video/x-raw(memory:NVMM),width=3264, height=2464, framerate=21/1, format=NV12' ! nvvidconv flip-method=2 ! 'video/x-raw,width=960, height=720' ! nvvidconv ! nvegltransform ! nveglglessink -e

2. If these commands don't succeed, give this a try:

sudo systemctl restart nvargus-daemon

Hi @tomek-l Everything is fine now and trying to upgrade to your program. At first I got an error in camera and tried to check the camera with this command ls /dev/video0. Anything have changed and got an error again, then try to install the video 4 linux utils with this command (sudo apt-get install v4l-utils) and then check video list (v4l2-ctl --list-devices). The output was fine. Thanks a lot for your kindly respond.

Hi Tomek-I!!! I want to get the Tavg data. But I don't know how can i get this Tavg data in your program. Where can i find the data set in your program? Thanks a lot!!! Waiting for your kindly reply.

Hi @Henery1 What version of torch , torchvision and python are you using? I'm having a problem with the version

I used Torch version 1.8.0 .
