Cannot enable tissue anymore. Numba install error

[NPDan87]

blender.crash.txt

After i enabled Numba, and it said installed succesfuly, i used tissue, after i closed it and opened blender it crashes instantly. Clean opening blender without any addons works fine, however i now cannot enable tissue without an instant crash of blender.

Is there a way to uninstall Numba? llvmlite seems to be the issue. I am a begginer at best in python and scripting but updating python3 and running: pip uninstall llvmlite fixed the issue. The addon can be used again with the message that numba module installed correctly.

Im preatty sure that what ive uninstalled should be used for something and i havent done a good job at this

i am using Ubuntu latest LTS up to date

Thanks great addon BTW

Hi @NPDan87 , Thanks for reporting that. Are you using the latest version of Blender from GitHub (master branch) or the one shipped with Blender? In theory llvmlite should be used for Numba. Removing it it's not ideal, but maybe is not used, I am not sure about that. Can you try importing Numba from the scripting console? Does it return any error? Have you successfully used the Reaction-Diffusion or the Tessellation?

>>> import numba "Traceback (most recent call last): File "", line 1, in File "/home/npdan/.local/lib/python3.10/site-packages/numba/init.py", line 19, in from numba.core import config File "/home/npdan/.local/lib/python3.10/site-packages/numba/core/config.py", line 16, in import llvmlite.binding as ll ModuleNotFoundError: No module named 'llvmlite'"

This is what i get when importing numba in blender, however it sais that its installed corectlly. Reaction diffusion works as it should however it maybe slower then it should linux console provs it

"119 Reaction-Diffusion: Plane Preparation Time: 0.009451627731323242 Not using Numba! The simulation could be slow. Simulation Time: 0.0333709716796875 Writing Vertex Groups Time: 0.012867450714111328"

After i reinstall llvmlite "pip install llvmlite Defaulting to user installation because normal site-packages is not writeable Collecting llvmlite Using cached llvmlite-0.39.1-cp310-cp310-manylinux_2_17_x86_64.manylinux2014_x86_64.whl (34.6 MB) Installing collected packages: llvmlite ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. numba 0.56.4 requires numpy<1.24,>=1.18, which is not installed."

Replacing the numpy version with one between the indicated versions, i tried with 1.23.5, installs well After that i try installing again llvmlite "pip install llvmlite Defaulting to user installation because normal site-packages is not writeable Requirement already satisfied: llvmlite in ./.local/lib/python3.10/site-packages (0.39.1)"

Now every version of blender i try it wont open printing the crash log from the original post, until i remove llvmlite To my very very very limited understanding about python this is due to differences in blenders version conflicts with ubuntu 22.04.02
