In other python distributions, this imports ok. On fedora linux, it actually looks like the tifffile module lies in skimage.external, which does not seem to exist on the macports version.

I can reproduce the error. As of version 0.17.0, scikit-image no longer bundles tifffile, and expects it to be installed separately. A port for it will need to be added to MacPorts and specified as a runtime dependency of the pyXX-scikit-image port.

I've got a py-tifffile port in my local tree. I'll push it later today.

[Schamschula (Marius Schamschula)]

I've added the py-tifffile port (and several dependencies) ​https://github.com/macports/macports-ports/commit/fe339b9afe4ad028e50b7693725a583aef74e589

py-scikit-image: add py-tifffile runtime dependency

See: #61178

I'm running into the same problem with py36-scikit-image, which declares a dependency on py36-tifffile, which is not addressed by the py-tifffile port file mentioned above.

Replying to barrettsa:

I'm running into the same problem with py36-scikit-image, which declares a dependency on py36-tifffile, which is not addressed by the py-tifffile port file mentioned above.

This should be resolved by [f01bfa8111/macports-ports] and [07fa310829/macports-ports].

I think this ticket can be closed.
