Dynamo crash while "Python Script" opening

[MarcinTata]

Hello. It happened to me first time. "Python from Script" is working and executes provided script. Background: lately I installed VisualStudio2017 with Python package.

Dynamo version

2.0.2.6826

Operating system

W10

What did you do?

I tried to open node "Python Script".

What did you see instead?

Error message.

Setting identificator of connectionId caused exception.

what python package have you installed in visual studio?

[MarcinTata]

Actually, I'm not sure if it was a 'package' or a set of templates. Anyway I chose it at the same step of installation were I chose version of Visual Strudio (2017).

Reinstallation of Dynamo does not help.

[mjkkirschner]

it's unclear to me if this has anything to do with your use of the python tools for vs.

• where are you using Dynamo, in revit?
• when you start dynamo do you see any green notifications in the dynamo menu? -Any about Avalon.Edit dll?
• what addins do you have installed for revit -?
• Do you have the same issues when you run DynamoSandbox?

The exception itself is unfortunately not too useful, it just points to some xaml loader code from .net. But this code is called when the python editor UI is called - which we use AvalonEdit for. I would start there looking for conflicts, like something else loading another version.

Hello,

• I use DynamoSandbox and Dynamo in Revit. Dynamo crashes while opening 'python script' node only outside Revit.
• No green dot, no notifications.
• I did't install any Revit Extensios/addins.
• Problem appears only in DynamoSandbox.

My packages:

• archi-lab.net
• BIM4Struc.Productivity
• BIM4Struc.Rebar
• BumbleBee
• Data-Shapes
• Dynamo Text
• DynaShape
• Simplex
• the-Saurus
• WombatDynamo

[mjkkirschner]

interesting - where are you running Sandbox from on disk? Have you built sandbox yourself or this is one that installed with DynamoRevit? Can you debug it to see the loaded modules?

[mjkkirschner]

also a first easy debugging step is to remove all the packages from your package folder and just place them outside of the package folder to see if the issue reproduces with all packages removed.

additionally - what versions of .net do you have installed?

[MarcinTata]

I run DynamoSandbox shortcut from desktop. DynamoSandbox is in C:\Program Files\Dynamo\Dynamo Core\2. Removing all packages from package folder WORKS.

Then I found a package that seems to mess with Dynamo: its Simplex. The package enables Dynamo to work with a few other programmes.

These are .NET versions:

Soooo: Simplex package is the problem.

[mjkkirschner]

is this package opensource somewhere?

[marcellosgamb]

I will work with mjkkirschner to resolve. The simplex package may have extra references that are not needed or may need to be split up Yes it talks with 4 databases Revit, SAP, ETABS, TEKLA

[mjkkirschner]

@marcellosgamb - please reopen this issue if you were not able to resolve the problem with the python node editor.
