raypyng 0.0.4

Python interface for RAY-UI x-ray tracing program

Install the package

Using virtualenv

0. Install python3:

sudo apt install python3 python3-venv python3-wheel -y

or (I still need to check ...)

sudo apt-get install python3-dev python3-pip python3-venv python3-wheel -y

1. Initialize virtual env:

python3 -m venv .venv

2. activate venv

3. install dependencies:

python3 -m pip install wheel

python3 -m pip install numpy psutil joblib matplotlib ipython schwimmbad

python3 -m pip install --upgrade  --index-url https://test.pypi.org/simple/  raypyng_test

Using conda

conda create -n raypyng_pkg python=3.9

conda activate raypyng_pkg

python3 -m pip install --upgrade  --index-url https://test.pypi.org/simple/  raypyng_test

conda install numpy psutil joblib matplotlib ipython

pip install schwimmbad

Install xvfb to run RAYUI headless

xvfb is a virtual X11 framebuffer server.

Install xvfb:

sudo apt install xvfb

Note: xvfb-run script is a part of the xvfb distribuion and runs an app on a new virtual X11 server

3. Install ray Download ray installer from https://www.helmholtz-berlin.de/forschung/oe/wi/optik-strahlrohre/arbeitsgebiete/ray_en.html. And run the installer...

4. History of resolving dependency issues:

Issue with the installer: missing libxkbcommon.so.0, searching solution:

lservice@ubjl-builder-01:~/projects/ray$ apt-file search libxkbcommon.so
libxkbcommon-dev: /usr/lib/x86_64-linux-gnu/libxkbcommon.so
libxkbcommon0: /usr/lib/x86_64-linux-gnu/libxkbcommon.so.0
libxkbcommon0: /usr/lib/x86_64-linux-gnu/libxkbcommon.so.0.0.0

Issue with rayui: missing libharfbuzz.so.0, search solution: libharfbuzz-dev: /usr/lib/x86_64-linux-gnu/libharfbuzz.so libharfbuzz0b: /usr/lib/x86_64-linux-gnu/libharfbuzz.so.0 libharfbuzz0b: /usr/lib/x86_64-linux-gnu/libharfbuzz.so.0.20600.4

rayui crashing with Abort(core dumed)

looking up: ldd rayui - seems to be OK looking up libs: ldd lib* : we got libxcb-render.so.0 not found

libxcb-render0 seems to be the answer ....

NOW IT WORKS!!!
