Hi @partnercloudsupport, that sounds great. Note that the lines you posted above are not an error. Namely, these are Caffe2 warnings saying that you have not compiled Caffe2 binary with avx support. This is relevant for running on the CPU and can be ignored in case of Detectron that runs on the GPU. The test now passes and you can proceed with the rest of the install/getting_started instructions.

Hi @partnercloudsupport, the caffe2.python.net_drawer warning can be safely ignored for the purpose of this test. Instead, the issue seems to be

File "/home/ubuntu/src/caffe2/caffe2/detectron/tests/test_spatial_narrow_as_op.py", line 29, in
import utils.c2
ImportError: No module named c2

Firstly, please make sure that you have set up Detectron python modules (run make) following the instructions from INSTALL.md.

Looking at your PYTHONPATH, it seems that it contains various Caffe2 subdirs which may be causing the issue (e.g. there may be a utils module under one of them). Try setting your PYTHONPATH to only contain the path to the Caffe2 build directory (PYTHONPATH=/path/to/caffe2/caffe2/build).

Also, it seems that you cloned the Detectron repo within the Caffe2 repo. I suggest you clone/keep your Detectron repo outside of the Caffe2 repo.
