I was able to successfully run cmake !cmake ..

but when I did make !make I got the following error

by the way caffe-gpu is installed via sudo apt install caffe-cuda

Did you add your caffe include path in your CMakeList.txt?

@2016110071 I am facing the same issue, I have installed caffe on Google Colab (Ubuntu 18.04 system with GPU) using "sudo apt install caffe-cuda" as described here: https://caffe.berkeleyvision.org/install_apt.html

I have two doubts: a) There are two CmakeLists files, one in the root directory itself and the other inside lib folder. The root folder CMakeLists file mentions a "thirdpart" folder and to an include/openblas folder. Where I can find these. b) Secondly I am unable to file a path location to the libcaffe.so mentioned in the lib/CmakeLists file, maybe its specific to Google Colab environment. My libcaffe.so.1.0.0 is at : /usr/lib/x86_64-linux-gnu/libcaffe.so.1.0.0 Caffe 2 is at : /usr/local/lib/python3.6/dist-packages/caffe2
