Image.new_from_file fails: parameter filename not set about pyvips HOT 5 CLOSED

Sorry, I don't know :( You could try running in a debugger and stopping on the first critical from glib.

I use it on macOS with vips from homebrew, then pip install pyvips and it works well with Apple's Python and with py3 from homebrew. Anaconda have their own package manager unfortunately and there is no libvips package. I've had a go at making one for bioconda, but not had time to finish it.

Which debugging commands would you recommend to use?

Well, I also first installed vips with brew and then did pip. I am NOT installing it with conda.
As brew distribution did not bind to the earlier installed openslide, I had to recompile everything. It still seems to be installed alongside with hand-compiled one. How can I see which one the pyvips is using?

I don't think you can mix anaconda and brew -- things will get horribly confused. You need a special vips package for anaconda, which sadly does not exist yet.

I would use brew with either Apple's Python, or the Python from homebrew itself.

My mac is a bit sick at the moment so I can't double-check :( I might be able to get it working later today.

Why so? To my understanding brew installs VIPS to the system and pip installs pyvips within the anaconda environment. Does VIPS installation per se modifies something in python / puts something in python local package repositories?

Brew will install stuff to /usr/local, but Anaconda won't load anything from there (I think?), and things like libjpeg, which libvips will try to load, will also exist within Anaconda's own binary area, and in the Apple one too. You'll get the wrong versions of almost every library :(

I think I would install the brew Python and try using pyvips from that. If that works, you'll know the problem is something to do with the way anaconda is doing things.

libvips is already packaged for homebrew, fink and macports, and now it looks like there will have to be an anaconda package as well. I wish Apple had a packaging standard everyone used :( having to maintain four packages on a single platform is an awful waste of time.
