Erro lab.create()

[nguyentheanhhnd]

I try run script:

server = Gns3Connector(url="http://localhost:3080")
lab = Project(name="check", connector=server)
try:
    lab.create()
    print("Project created successfully")
except ValueError as e:
    print(f"Error creating project: {e}")
print(server.projects_summary())
print(lab.status)

this is erro :
python3 vidu2.py

During handling of the above exception, another exception occurred:

Can you post the version of GNS3 you are using and the version of pydantic as well?

[nguyentheanhhnd]

I am currently using GNS3 version 2.2.44.1, Python 3.8.10, and Ubuntu 20.04.6 LTS.

I'm also having difficulty with node creation and link creation. Do you have any examples for this? thank you

[davidban77]

Here is a link to the documentation for node creation: https://davidban77.github.io/gns3fy/user-guide/#node-creation

Link creation is just after it.

I had the same error, using 'pip install gns3fy' on Ubuntu 20.04.
A dirty hack is to get the newest version of 'gns3fy.py' from GitHub (either clone the repos or make a raw copy of the file).
Then overwrite the existing file (which seems to be /usr/local/lib/python3.8/dist-packages/gns3fy/gns3fy.py in your case).

This fixes the 'pydantic_initialised was unexpected' error.

The "proper" solution (according to the documentation) to install the cloned GitHub version is using 'poetry', but this doesn't seem to work with Python 3.8.
