How to force install Dlib with only CPU support on a GPU machine with Cuda enabled

[rsadiq]

Hello,
I am trying to install Dlib CPU version on a GPU machine with Cuda and everything installed and working. But even when I try to install from source and using the flag to not use CUDA, but it still is using Cuda.

On internet and issues, all I can see is problem with using Cuda. I can use Cuda and I don't want that.

Expected Behavior

It should not use Cuda and only go for cpu

Current Behavior

But Dlib after installation tries to use GPU.

Steps to Reproduce

I am using Google Colab which by default provide us Dlib, so I am uninstalling it.
!pip uninstall dlib
!pip uninstall face_recognition

if you are in directory where you previously cloned Dlib, remove it

!rm -r dlib/
!git clone https://github.com/davisking/dlib.git
%cd dlib
!mkdir build
%cd build
!cmake .. -DDLIB_USE_CUDA=0 -DUSE_AVX_INSTRUCTIONS=1
!cmake --build .
%cd ..
!python setup.py install --no DLIB_USE_CUDA

The builds and install successfully and I can import Dlib
!pip install face_recognition
import dlib
import face_recognition

RuntimeError: Error while calling cudaGetDevice(&the_device_id) in file /tmp/pip-install-9p_kkgzg/dlib/dlib/cuda/gpu_data.cpp:178. code: 38, reason: no CUDA-capable device is detected

PS: When I change my runtime to GPU it works fine, since it finds GPU. But when I set the runtime as TPU or CPU it can not find GPU obviously since it was built for GPU.
So how can we force Dlib to use only CPU even on GPU machine

[davisking]

If you are installing the python API, you don't need to run cmake.

When you run python setup.py install --no DLIB_USE_CUDA it will print a bunch of stuff, some of it will talk about cuda and say if it's turning cuda on or off. It should say it's turning it off. The issue is almost certainly that you have multiple copies of dlib installed still and are using the one that was built with cuda enabled, rather than the one you just built.

Hello Davis,
Thank you for your response.
I made sure that i have removed every copy of dlib before fresh start.
and confirmed it by
import dlib

python setup.py install --no DLIB_USE_CUDA does not show if the CUDA is off or on, But if we dont use it, it does show that its looking for CUDA, So i assume that its not using it. And after trying out all the things, the thing that worked for me is: "REBOOT THE SYSTEM".
Sorry for opening the issue before doing it. Closing it as it is not an issue. We can use Dlib with CPU on GPU machine and we have to build from source.
**A suggestion: May be via PIP install, we can have an option to install CPU or GPU version as per choice ? like tensorflow and tensorflow-gpu ?

[davisking]

Use pip's --install-option. Like sudo pip install -v --install-option="--no" --install-option="DLIB_USE_CUDA" dlib. See https://pip.pypa.io/en/stable/reference/pip_install/

This is what happens when i try pip install without CUDA..

The similar thing happens when i try to install it with setup.py:
#109

Is it my dependencies?

The similar thing happens when i try to install it with setup.py: #109

Is it my dependencies?

sudo apt-get install python3-dev
should do the trick for you.
