LM3.1.0 error on line 266 of s2_buildNetwork.py

[杨鹏]

Hi，i run  LM3.1.0  in Arcgis Pro. And i always got the error. i read the conversation at  https://groups.google.com/g/linkage-mapper/c/3yBVXwaQdpk  . but  i did not solve this problem.

my .txt file  as follow

********************************************************
NOTE: ArcGIS errors are more likely when writing to remote drives or deep file structures. We recommend shallow project directories on local drives, like C:\puma. Errors may also result from conflicts with anti-virus software (known problems with AVG). We have also seen conflicts when writing to synchronized folders like DROPBOX.

Note also that Linkage Mapper tools often work best when run from ArcCatalog instead of ArcMap.

your error.txt file is showing up blank, and your copy and paste of the log file looks incomplete.  it is possible that you have two versions of the software on your computer, and yor toolbox is linking to the old one.

 I suggest you delete the old version of the software from your computer (or at least move it to a "temp" folder) , and you download and use v 3.1 , from here: https://linkagemapper.org/Downloads/ 

And whenyousend the log file, please tryt again as an attachment, but back it up with a copy and paste in the email, but include every character/word please.

Thank you ,

John

Thanks for your help.
Finally, i found the solution about my problem.
 Because my core area is outside the resistance surface.
i used this tool sucessfullly when i changed my core area.
