Cannot complete installation of Blender

Pablo

I'm getting problems to finalize the installation of the Blender add on in different computers.

In a PC I have this error

`WARNING: You are using pip version 19.2.3, however version 22.3.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
2022-12-27 18:11:57,239 - ERROR - Error installing python dependencies for the Chordata add-on.
    It might be due to a temporary connectivity issue.
    Please check your connection and try again.
    If the problem persists please report the error on the Chordata forum pasting the output from the system console

On a MAC I'm getting an error when trying to connect the Notochord node.
Initially it says it will install some dependencies, but after that there's an error from base.py, engine.py, armature.py armature_manager.py

"chordata.defaults.Calibration_error: Dependencies not found"
location: <unknown location>:-1

How can I solve this?

Hello Pablo

In the PC there might be a firewall blocking blender from connecting to the internet.

Could you try executing these two lines from the internal blender console?

import requests
requests.get("http://chordata.cc")

you should get a 200 response if blender can access the net.

If that's not the problem could you try a more recent version of blender? the current version of the addon was mainly developed and tested on blender >3.0

Which version of blender are you using on your mac?

Or, as @zaanen suggested in this post the PC running blender itself should be connected to the internet, if your are connected to the Chordata-net WIFI network you won't have internet access

Pablo

Hi! Yes, you need to be both connected to the chordata network and internet in order to make it work. I recommend you to put that in the Getting started since it's an important step and it takes some preparation, i.e. you need another source of internet like a LAN cable in order to do it.
Thank you!

Yes, we will do that. Thanks for your feedback!

hi, I have trouble making the Blender add-on work too.
After calibrating one Kceptor, I followed the "Test Kceptor calibration" in the doc and I'm stuck at step 4, when I pressed Connect, it says:

Chordata Engine (v1.2.0, #d6e6258d) started @ 2023-01-05 00:23:35
Sending configuration
Activating configuration

HTTP error

POST http://notochord:80/state
status code: 0
Chordata Engine stopped

It seems the dependencies for the Blender add-on have been installed.
Any pointer here is appreciated guys

hello Tkthlntc
I'm sorry I missed this one (we are receiving tons of spam lately in this forum, so we have an aggresive spam filter that somehow flagged this one)

I guess this is related to the issue we are discussing in this other thread let me know how it goes
