Python3 API not using cudnn even if it is used by other frameworks like Tensorflow. #1259

Closed urvishp80 closed 6 years ago

urvishp80 commented 6 years ago

I am on Ubuntu 16.04 and using Tensorflow and keras lot in development. I want to use Dlib's face detector with GPU support but when I started installing dlib using this command :- python setup.py install --yes USE_AVX_INSTRUCTIONS . I got message that cudnn is not found and you can specify the path using Cmake_PREFIX_PATH or something like that. I do not remember that exactly and kill the terminal eventually. So how can I use that this Cmake command to install dlib with cuda support ?

I have tried various forums and whatever I can possibly think of but did not get any success. So it will be great if anyone can provide me clean command to install dlib with cudaa support.

If you are the OP from https://stackoverflow.com/questions/49841147/why-i-get-dlib-isnt-going-to-use-cuda-when-i-compile-dlib-python-interface then the reason you aren't getting help is because you aren't answering the questions people ask.

In particular, what happens when you run python setup.py build --clean? Post the complete output.

Thank you for your quick reply.I am not that person. I run the above command as you have mentioned that is python setup.py build --clean and I got this output `sudo python3 setup.py build --clean running build running build_py package init file 'dlib/init.py' not found (or not a regular file) running build_ext Removing old directory /home/urvish/Documents/dlib/build/temp.linux-x86_64-3.5 Invoking CMake setup: 'cmake /home/urvish/Documents/dlib/tools/python -DCMAKE_LIBRARY_OUTPUT_DIRECTORY=/home/urvish/Documents/dlib/build/lib.linux-x86_64-3.5 -DPYTHON_EXECUTABLE=/usr/bin/python3 -DCMAKE_BUILD_TYPE=Release' -- The C compiler identification is GNU 5.4.0 -- The CXX compiler identification is GNU 5.4.0 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Found PythonInterp: /usr/bin/python3 (found version "3.5.2") -- Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython3.5m.so -- Performing Test HAS_CPP14_FLAG -- Performing Test HAS_CPP14_FLAG - Success -- pybind11 v2.2.2 -- Using CMake version: 3.5.1 -- Enabling SSE4 instructions -- Looking for pthread.h -- Looking for pthread.h - found -- Looking for pthread_create -- Looking for pthread_create - not found -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found -- Found Threads: TRUE

No BLAS library found so using dlib's built in BLAS. However, if you install an optimized BLAS such as OpenBLAS or the Intel MKL your code will run faster. On Ubuntu you can install OpenBLAS by executing: sudo apt-get install libopenblas-dev liblapack-dev Or you can easily install OpenBLAS from source by downloading the source tar file from http://www.openblas.net, extracting it, and running: make; sudo make install

davisking commented 6 years ago

What happens when you build dlib/cmake_utils/test_for_cudnn? That's the project that is failing and giving this error. If you build that project with cmake you will be able to see the specific errors and why it thinks you don't have cuDNN installed.

urvishp80 commented 6 years ago

I do no know how to do that so I did not do that. Can you help me with that? I do not have much understanding of cmake and how it works. Guide me in this.

davisking commented 6 years ago

Go into the folder, make a subfolder, call it anything. build is a good name. Then from within that folder run cmake .. and then type make

urvishp80 commented 6 years ago

I have created folder build1 and within that folder I run the command cmake .. and I got his output

No

cd dlib/cmake_utils/test_for_cudnn
mkdir build
cd build 
cmake ..
make
urvishp80 commented 6 years ago

Done that and this is the output of cmake ..

Well, I don't believe that you have cuDNN installed. You need the cudnn development package installed, the one with the header files. You get it from the nvidia website.
