I am a Windows user and I have been trying to install cadabra2 for some time.
After attempting to install using both available wizards (-f and -g versions), and failing, I decided to try the installation on the Windows Subsystem for Linux (WSL), running Ubuntu 18.04.
Firstly I tried to install from source and downloaded the needed components from github, following the instructions Kasper wrote there. Cadabra2 works just fine from command line, but the graphic interface cadabra2-gtk freezes whenever I try to compile the code (on the other hand I can edit/open/save notebooks). (I need to use a virtual display to access the user interface from WSL).
Then I tried to install jupyter and run cadabra2 from the cadabra-jupyter-kernel. The same problem occurs: attempting to launch commands that require the cadabra kernel to run result in a connection error and the notebook staying idle.
Other attempts: I tried to uninstall and reinstall everything via miniconda/anaconda. Amusingly enough, I cannot run conda install cadabra2 from the "home" environment, which results in a failure to properly detect the environment, but I need to create a new environment. In the end I obtaining analogous results as from the installation from source both for cadabra2-gtk and jupyter notebook.
I also tried disabling the Windows firewall, but to no avail.
I really would like to use cadabra2, since it really looks awesome, but I keep stumbling on different installation issues... Please help!
