Broken extras "taurus-h5file"

Hi everyone

I'm trying to create rpm packages of taurus via new Fedora guidelines, which requires to handle all extras provided by upstream. According to setup.py, the latest taurus has 5 extras: taurus-qt, taurus-pytango, taurus-epics, taurus-h5file and taurus-qt-editor (and pypi knows about it). The problem with taurus-h5file: if I'm trying to install it casual way like:

pip install taurus[taurus-h5file]

I've got wierd pip behaviour:

[microfocus@microfocus-operator-pc1 ~]$ pip install taurus[taurus-h5file]
Defaulting to user installation because normal site-packages is not writeable

Looks like pip cannot manage additional deps and downgrades taurus version until it won't have h5file extras.

I think proposed extras is outdated and should be removed on edited.

Thanks
