[Bug]: python setup.py install (_dlib_pybind11: not found error) / pip install dlib (CUDA disabled error) #2979
Comments

Hard to say, but something about your compiler or cuda install is broken. Which is out of control of dlib. Do this to find out more: and see why that test program fails to build. It's just a trivial cuda program so you have to figure out why your computer is not capable of building it. All dlib's installer is doing is running that test build and if it fails it prints that message about not being able to use cuda. |

Hard to say what's wrong with your system. But do |
|
Unfortunately, the same error mentioned occurs. ImportError: DLL load failed while importing _dlib_pybind11 |
I commented on a closed issue of the same thing. I happened to find the fix. I found the fix for this. At least on windows for me.
I am using the latest from below Visual Studio 2022 Install the CUDA toolkit first and reboot. After install the cuDNN. With system variables like these Now in the directory Move all the 12.6 files from If you're using tensorrt as well then you want to extract the zip and move all files and folders to Then you want to copy the file like the stackoverflow says (for me it was this)
Then
You should see
Then
Run the following command from the source directory
and then another output like
A successful build then ends with
After all is said and done Python 3.11.9 (tags/v3.11.9:de54cf5, Apr 2 2024, 10:12:12) [MSC v.1938 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import dlib
>>> print(dlib.DLIB_USE_CUDA)
True

I highly appreciate your detailed steps! It works! Based on my different combinations of configurations, these steps are crucial after the installation of CUDA and cuDNN:
But actually, I did not do this. I did the following: Firstly, I added the system variable CMAKE_PRIFIX_PATH whose value is "C:/Program Files/NVIDIA/CUDNN/v9.4". Secondly, reboot. Thirdly, run 'python setup.py install' from the source directory. I searched the internet and found that the bizarre error may be related to the upgrade of Nvidia's cuDNN. When users install cuDNN 8.x - 1.x which are provided as zip files, the tutorials existing on the internet tell users to move the files in the Consequently, I think the Tarball installation guide and your suggestions are correct. |
Yeah I am knew to all this and I found out if making the python whl you dont need to do the cmake. But I guess it does not hurt lol |
What Operating System(s) are you seeing this problem on?
Windows
dlib version
19.24.0 19.24.1 19.24.2 19.24.3 19.24.4
Python version
3.7 3.8 3.9 3.10 3.11 3.12
Compiler
MSVC 19
Expected Behavior
import dlibwithout errorsdlib.DLIB_USE_CUDAreturns TRUECurrent Behavior
Environment
win11
Cmake 3.29.6
CUDA 12.5
cuDNN 9.2
I have tested my CUDA installation in different ways (including testing in PyTorch). The CUDA works fine.
python setup.py installerrorIf I run
python setup.py install, the terminal says thedlibis installed successfully. And the terminal logs:However, the dilb is NOT indeed installed successfully.
When I use
import dlibin a .py file, the terminal showserror: ImportError: DLL load failed while importing _dlib_pybind11: not found, as is described in #2977pip install dlib --verboseerrorIf I run
pip install dlib --verbose, the terminal saysCUDA was found but your compiler failed to compile a simple CUDA program so dlib isn't going to use CUDA.However, the dlib is indeed installed.
I can use
import dlibin a .py file without error. Butdlib.DLIB_USE_CUDAreturnsfalse.Steps to Reproduce
run
pip install dlib --verboseor
run
python setup.py installfollowing http://dlib.net/compile.html
Anything else?
I have tested using Python 3.7/3.8/3.9/3.10/3.11/3.12 and dlib 19.24.0/19.24.1/19.24.2/19.24.3/19.24.4, all these tests come with the same problem.
