problem with pasta

[ChaoShenzjs]

hi there,
I installed pasta in a linux system following the instruction, it seems successful. but when I try run_pasta.py and some problems occcured showed: ImportError: cannot import name convert node to root polytomy. How do deal with it?
Many thanks!

I came across a similar issue, being the following python error (using Python 3.10):

ImportError: cannot import name '_convert_node_to_root_polytomy' from 'dendropy.datamodel.treemodel'

This is due to an update in Dendropy (a dependency of PASTA) from v4.5.1 to v4.6.0. Installing specifically Dendropy v4.5.1 (eg. python -m pip install dendropy==4.5.1) solved this issue for me.

Actually version 4.5.2 works as well as this comment says: smirarab/sepp#126 (comment)

I'll create a pull request to set this version as a dependency and a new issue to adapt pasta code for the newest version of dendropy.

6f3ff89 fixes for now. We use issue #67 to track this. So, I'll close this one.
