Google Colab CMake Warning

[deyviddfs]

Hi @nagadomi, I got an error to run Torch Lua in Google Colab.

I have tried to downgrade the cuda to version 10, but I didn't succeed.

I had that error

CMake Warning (dev) in CMakeLists.txt:
No project() command is present. The top-level CMakeLists.txt file must
contain a literal, direct call to the project() command. Add a line of
code such as

project(ProjectName)

near the top of the file, but after cmake_minimum_required().

CMake is pretending there is a "project(Project)" command on the first
line.
This warning is for project developers. Use -Wno-dev to suppress it.

CMake Warning (dev) in CMakeLists.txt:
cmake_minimum_required() should be called prior to this top-level project()
call. Please see the cmake-commands(7) manual for usage documentation of
both commands.
This warning is for project developers. Use -Wno-dev to suppress it.

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 3.5 will be removed from a future version of
CMake.

Update the VERSION argument value or use a ... suffix to tell
CMake that the project does not need compatibility with older versions.

CMake Deprecation Warning at exe/luajit-rocks/CMakeLists.txt:9 (CMAKE_MINIMUM_REQUIRED):
Compatibility with CMake < 3.5 will be removed from a future version of
CMake.

I did downgrade with that code

!wget https://developer.download.nvidia.com/compute/cuda/10.2/Prod/local_installers/cuda-repo-ubuntu1804-10-2-local-10.2.89-440.33.01_1.0-1_amd64.deb
!dpkg -i cuda-repo-ubuntu1804-10-2-local-10.2.89-440.33.01_1.0-1_amd64.deb
!apt-key add /var/cuda-repo-10-2-local-10.2.89-440.33.01/7fa2af80.pub
!apt-get update
!apt-get install cuda-10-2
!export CUDA_PATH=/usr/local/cuda-10.2/
!nvcc --version

Could you help me?

Thank you!
