CMake error while installing Torch in Ubuntu
Solution 1
The cublas_device
library was deprecated in CUDA 9.2 and removed in CUDA 10. Looks like your version of Torch is building against cuDNN that is expected to work with CUDA 9.2 or older.
You can either:
- Use this fork of Torch that works with CUDA 10 https://github.com/nagadomi/distro
- Downgrade to CUDA 9.2 or older
Another aspect that you need to be aware of is to ensure your NVidia GPU driver, cuDNN and CUDA versions all works together. Refer to https://docs.nvidia.com/deploy/cuda-compatibility/index.html.
Solution 2
https://github.com/nagadomi/waifu2x/issues/253#issuecomment-445448928
git clone https://github.com/nagadomi/distro.git ~/torch --recursive
cd ~/torch
./install-deps
./clean.sh
./update.sh

I'm trying to install Torch in my PC (Ubuntu). I follow the steps described in the Torch website. However, when I run
$./install.sh
I got the error:
CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: CUDA_cublas_device_LIBRARY (ADVANCED) linked by target "THC" in directory /home/leonardo/torch/extra/cutorch/lib/THC
So I tried to analyze the CMake log and there is this following error:
/home/leonardo/torch/extra/cutorch/build/CMakeFiles/CMakeTmp/src.c:5:20: error: ‘luaL_setfuncs’ undeclared (first use in this function); did you mean ‘lua_setfenv’? long i = sizeof(&luaL_setfuncs); ^~~~~~~~~~~~~ lua_setfenv /home/leonardo/torch/extra/cutorch/build/CMakeFiles/CMakeTmp/src.c:5:20: note: each undeclared identifier is reported only once for each function it appears in CMakeFiles/cmTC_0eb19.dir/build.make:65: recipe for target 'CMakeFiles/cmTC_0eb19.dir/src.c.o' failed
Why I have got this error? And how can I resolve it?
Sorry for my english, it's a little rusty, if anyone can't understand it, tell me to explain all of this in another way. Thanks for everyone who helps me with it.
PS: I installed NVidia CUDA Toolkit before all of it, maybe the Torch is "strange", because of it.

Tsyvarev over 5 yearsThe "CMake Error" you got means that a library, corresponded to
CUDA_cublas_device_LIBRARY
variable, hasn't been found. According to variable name, this iscublas_device
library. I am not expert in CUDA, so cannot suggest where to search this library and even if it should exist. But the project requires it. As for the compilation error inCMakeLog.txt
, it is most likely just a check, whether function/variableluaL_setfuncs
exists. Depending on the check results, the project should configure itself accordingly. No worries in that.

Chris almost 4 yearsAnd after ./update.sh, use . ~/torch/install/bin/torch-activate to activate torch
