Lack of graceful error handling #30
Description
In light of #28 and #29, I would also like to highlight some other parts in the program that show a lack of graceful error handling mechanisms.
For this issue, when the Z-Image model could not be found at the specified (default) search path, instead of aborting immediately, the program still attempts to continue anyway as it gradually crumbles until it hits a SIGFPE - presumably a division-by-zero, judging by the backtrace, because no data was loaded even if the code assumes so.
Usually, the program would have checked if the model files are even there in the first place and aborted if it can't read the model files for any reason, rather than just assume that the open calls would never fail.
While I couldn't reproduce this particular behavior for now, at one point the program could even "continue" while hallucinating forward passes until it couldn't anymore.
