How to install PyOptix from the source? #3

Closed kaanaksit closed 6 years ago

kaanaksit commented 6 years ago

Here is a copy of my journal on how I approach trying your library on my system, at the end you will also find the problem that I am facing currently with the installation:

I started usin NVIDIA OptiX 5.1 version and Ubuntu 16.04:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.4 LTS
Release:    16.04
Codename:   xenial

Download OptiX from this website:

https://developer.nvidia.com/optix

This will install a file called NVIDIA-OptiX-SDK-5.1.0-linux64_24109458.sh or similar depending on the version that you are downloading. Extract the content using:

$ cd Downloads
$ chmod +x NVIDIA-OptiX-SDK-5.1.0-linux64_24109458.sh
$ ./NVIDIA-OptiX-SDK-5.1.0-linux64_24109458.sh
$ cd ~
$ sudo cp -R NVIDIA-OptiX-SDK-5.1.0-linux64 /usr/local/

Make sure that you have Optix in your LD_LIBRARY_PATH:

$ echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/NVIDIA-OptiX-SDK-5.1.0-linux64/" >> ~/.bashrc

Make sure you have everything you need for PyOptix:

$ sudo apt-get install -y build-essential python-dev python-setuptools python3-dev python3-setuptools libboost-python-dev

Make sure that you have nvcc:

$ nvcc --help

And install PyOptix using pip3:

pip3 install pyoptix

This is what I got at the end:

Hi Kaan,

Library path should be /usr/local/NVIDIA-OptiX-SDK-5.1.0-linux64/lib64 (you are missing lib64 at the end). This is where library files are located (specifically liboptix.so library file is what we need).

Hi Ozen,

Thank you very much for your quick response. Here is what happens when I correct the path:

Hi Kaan,

sudo sanitizes the environment before invoking the command. So, LD_LIBRARY_PATH is empty when setup script is run.

There are various ways to preserve environment variables while using sudo. You can look it up. I think adding -E option should work.

kaanaksit commented 6 years ago

Hi Ozen,

Thank you very much for your quick response. Is my assumption correct here? Since I have the LD_LIBRARY_PATH in an updated way at my .bashrc, when I start a new shell my LD_LIBRARY_PATH set to correct values as shown below:

:PyOptiX$ sudo echo $LD_LIBRARY_PATH
:/usr/local/cuda/lib64:/usr/local/cuda/lib64:/usr/local/lib/python3.5/dist-packages/openvr-1.0.801-py3.5.egg/openvr/:/home/kaan/.steam/steam/steamapps/common/SteamVR/bin/linux64:/home/kaan/.steam/steam/steamapps/common/SteamVR/tools/bin/linux64:/usr/local/NVIDIA-OptiX-SDK-5.1.0-linux64:/usr/local/NVIDIA-OptiX-SDK-5.1.0-linux64/:/usr/local/NVIDIA-OptiX-SDK-5.1.0-linux64/lib64
:PyOptiX$ echo $LD_LIBRARY_PATH
:/usr/local/cuda/lib64:/usr/local/cuda/lib64:/usr/local/lib/python3.5/dist-packages/openvr-1.0.801-py3.5.egg/openvr/:/home/kaan/.steam/steam/steamapps/common/SteamVR/bin/linux64:/home/kaan/.steam/steam/steamapps/common/SteamVR/tools/bin/linux64:/usr/local/NVIDIA-OptiX-SDK-5.1.0-linux64:/usr/local/NVIDIA-OptiX-SDK-5.1.0-linux64/:/usr/local/NVIDIA-OptiX-SDK-5.1.0-linux64/lib64
kaanaksit commented 6 years ago

Ok, now I get to be able to compile it successfully. In my case trick was to add this alias at the end of .bashrc:

alias sudo='sudo PATH="$PATH" HOME="$HOME" LD_LIBRARY_PATH="$LD_LIBRARY_PATH"'

and run the setup one more time:

:PyOptiX$ sudo python3 setup.py install

What is the proper way to run examples?

kaanaksit commented 6 years ago

Ok, I had to do a small manipulation to get the example running. I simply navigate to ~/PyOptiX/examples/hello and edited hello.py file. Replace this line:

sys.path.append(dirname(dirname(dirname(__file__))))

with these lines:

dir = '../../'
sys.path.append(dir)

and what I get was a green screen when I call:

:hello$ python3 hello.py

This resolves it all. Ozen thank you very much for all your help. I may be shooting new questions to you in the near future as I am evaluating your library for my next project.

Çok teşekkür ediyorum.
