Installations

Blender

  • If downloaded using the terminal: it’s already done 👌

  • If downloaded from the website (not recommended here):
    → As mentioned here, uncompress the content of the downloaded .tar.xz at the desired location (e.g. ~/software or usr/local)

  • Launch it to check if everything went well 😉

Anaconda

    • Open a new terminal where the file is saved.
      → Then enter: bash file_name.sh
      → Where file_name = anaconda.sh or Anaconda3-[version]-Linux-x86_64.sh, depending on wether you downloaded it using the terminal or the website.
    • During the installation:
      → You can choose a custom location for the Anaconda installation files.
      However, this tutorial uses the default location (recommended).
      → Do you wish the installer to initialize Anaconda3? → yes

    • Once the installation is finished: source ~/.bashrc

Anaconda environment and Blender

In this part, we will create a new conda environment and install the necessary packages for Quantum Nodes. Then, we will tell Blender to use our environment instead of the python that comes with by default.

  • Open a new terminal:
    → Go to your Blender files.
    The files are located here (when installed using the terminal): cd /usr/share/blender/2.91/

  • Deactivate the current python version: mv python _python

  • Create a new Anaconda environment:

Warning : as mentioned here, the python version (major and minor) must match the one that Blender comes with. For Blender 2.91.2, python 3.7 is ok.

 
→ Enter : conda create --name=blender python=3.7
→ When the installation is finished, enter: conda activate blender
  • Link the Anaconda environment to Blender:
    → If you have installed Anaconda with the default parameters, as we did in this tutorial, your conda env’ should be installed here: ~/anaconda3/envs/blender/
    → So, enter: sudo ln -s ~/anaconda3/envs/blender/ python
    This creates a junction between the python folder in the Blender files and the folder in the Anaconda environments files.
  • Install the needed python packages for Quantum Nodes:
    pip install pillow
    pip install scipy
    pip install qiskit
  • Then, open Blender, go to scripting and type in the python console: import qiskit
    If Blender does not find Qiskit, you need to follow the next steps:
    → Go here: cd ~
    → Enter: sudo nano .bashrc
    → Insert this line at the end (use arrows to scroll down): export PYTHONNOUSERSITE=True
    → Close the document : ctrl + x then y and enter
    → Reopen Blender, it should now find Qiskit.
