cannot import name 'TPyMultiGenFunction' from 'ROOT'

Hello,

If pyroot_experimental=ON then there is a problem:

In [1]: import ROOT

In [2]: from ROOT import TPyMultiGenFunction
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-2-a652b5423d9f> in <module>
----> 1 from ROOT import TPyMultiGenFunction

ImportError: cannot import name 'TPyMultiGenFunction' from 'ROOT'

If pyroot_experimental=OFF then everything is ok.

Cheers,

Jiri
