Hello @laganojunior
Thanks for reporting it.
There was a bug in yuv to rgb conversion, the fix was landed in master recently [android] Fix YUV camera image to tensor by IvanKobzarev · Pull Request #50871 · pytorch/pytorch · GitHub
Next nightly build of
implementation 'org.pytorch:pytorch_android_torchvision:1.8.0-SNAPSHOT'
will contain that fix.
