Re: [Ecell-users] ecell-3.2.3pre2 AttributeError

[Yasuhiro N. <yn...@sf...>]

Dear Lu,

Another way is downgrading E-cell to ver 3.1.x.

You can download the latest version of E-Cell 3.1.x from GitHub [ecell/ecell3 branch:ecell-3.1].
https://github.com/ecell/ecell3/tree/ecell-3.1 (ZIP download)

You should run ./autogen.sh before ./configure .
I installed it just now on the latest Ubuntu, and successfully run the model including PythonProcess.

We are sorry for the inconvenience.

Regards,
Yasuhiro
