trouble in installation

[rafikg]

I am working under ubuntu 18.04 using anaconda 3. I create a conda environment and I run correctly the test until the make ops command where I have a problem
I set CMAKE_PREFIX_PATH=/xxx/yyy/anaconda3
**CMake Error at CMakeLists.txt:8 (find_package):
By not providing "FindCaffe2.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Caffe2", but
CMake did not find one.

Could not find a package configuration file provided by "Caffe2" with any
of the following names:

Caffe2Config.cmake
caffe2-config.cmake

Add the installation prefix of "Caffe2" to CMAKE_PREFIX_PATH or set
"Caffe2_DIR" to a directory containing one of the above files. If "Caffe2"
provides a separate development package or SDK, be sure it has been
installed.**

hi@Gouiaa,l also encouter this problem,have you solved this trouble?

[rafikg]

@Anikily Yes.You have to set correctly the CMAKE_PREFIX_PATH.
find the folder path that contains Caffe2Config.cmake (should be something like /share/cmake/caffe2/) and add this line at the beginning of the CMakeLists.txt file.
set(CMAKE_PREFIX_PATH "path of the folder that contains Caffe2Config.cmake")

Thanks Gouiaa,I have solved this problem by
set(Caffe2_DIR "/path/to/pytorch/torch/share/cmake/Caffe2/")
and i think it is the right way to do.
but i have some trouble new:
mkdir -p build && cd build && cmake .. && make -j12

and about the problem: /home/tensor/densepose/detectron/ops/pool_points_interp.h:13:33: fatal error: caffe2/core/context.h: No such file or directory
actually,i find the context.h in pytorch/caffe2/core/context.h,could this file not be found?
