Dlib: --yes not accepted as a command ?

[thakurritesh19]

Current Behavior

I am trying to install dlib with CUDA support. However upon running this command post cmake gives following error:
Command I am running: sudo python3 setup.py install --yes USE_AVX_INSTRUCTIONS --yes DLIB_USE_CUDA
Error: The --yes options to dlib's setup.py don't do anything since all these options
are on by default. So --yes has been removed. Do not give it to setup.py.

Now I thought removing --yes parameters would solve it but it gives me this prompt:
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands
or: setup.py cmd --help

error: invalid command 'USE_AVX_INSTRUCTIONS'

At this point I am not sure on how to run the setup.py to finally install it using CUDA support.

Please note I have faced no issues in building dlib using cmake. All the steps that come before it, didnt fail for me.

I have all the dependencies installed too.

Expected Behavior

I expect to install dlib using CUDA on my Ubuntu 16.04.

Steps to Reproduce

I am installing dlib using CUDA using this process here:

$ git clone https://github.com/davisking/dlib.git
$ cd dlib
$ mkdir build
$ cd build
$ cmake .. -DDLIB_USE_CUDA=1 -DUSE_AVX_INSTRUCTIONS=1
$ cmake --build .
$ cd ..
$ python setup.py install --yes USE_AVX_INSTRUCTIONS --yes DLIB_USE_CUDA

• Version: Master on current git repo
• Where did you get dlib: github
• Platform: Ubuntu 16.04 64 bit
• Compiler: gcc and g++ 5.4.0

Have you tried not passing --yes, as suggested? That option was removed, take a look at the release notes: http://dlib.net/release_notes.html

Hey arrufat,

Yes. Like my post says, not passing yes has different error:

Now I thought removing --yes parameters would solve it but it gives me this prompt:
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands
or: setup.py cmd --help

error: invalid command 'USE_AVX_INSTRUCTIONS

[arrufat]

Yes, USE_AVX_INSTRUCTIONS isn't a valid option either, so why not check the options on the setup.py file? It seems that you need to pass --set before that...

Can you please elaborate on this? I do not understand what needs to be done. I am also having the same error, but on:
Ubuntu 18.04
gcc-6 and g++-6

use the below command:
python setup.py install

[CyanideCentral]

These options are on by default now. To explicitly turn them on, try this instead:
python setup.py install --set USE_AVX_INSTRUCTIONS=1 --set DLIB_USE_CUDA=1

[davisking]

Don’t do either of these. These things are set automatically.

[leobobsix]

None of these suggestions above is working for me. I have deleted dlib in site-packages and build file in dlib directory. Then, re-build files and re-run setup.py with and without --set parameters.

python setup.py install --set USE_AVX_INSTRUCTIONS=1 --set DLIB_USE_CUDA=1

python setup.py install

At last, I run print(dlib.DLIB_USE_CUDA) and still get a false

[iamkhadka46]

just use "python setup.py install". like it says it is set by default so no need to "set" anything.

[Muhammad-Hasham-Khalid]

I enabled the USE_CUDA and USE_AVX_INSTRUCTIONS flag when building dlib using cmake, then, I just used this command to install it:

python setup.py install

but it is still printing dlib.DLIB_USE_CUDA as False when i do this

import dlib
print(dlib.DLIB_USE_CUDA)

I was having the same problem. I redid the installation repeatedly, until I was sure I was doing it correctly, but dlib.DLIB_USE_CUDA remained False.

I finally figured out that there were two problems.

• I'd installed some CMake utilities in Visual Studio Code. Apparently dlib doesn't like these. Removing them and installing Visual Studio C++, then making sure CMake was in the environment variables path made compilation go a lot more smoothly.
• Anaconda had its own version of dlib, which I'd apparently installed at some other point. So when I thought that I was using one version, I was actually using another.
• After fixing these, DLIB_USE_CUDA is true.

Maybe this will help someone in the future.
