You are most welcome @Ahmed_Ramy! Glad it was helpful
Hi Sol! After following your steps, unfortunately this error was thrown :
*" Warning: ImportError : *
IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
-
https://numpy.org/devdocs/user/troubleshooting-importerror.html*
Please note and check the following: -
- The Python version is: Python3.8 from “C:\Program Files\Autodesk\AutoCAD 2022\C3D\Dynamo\Core\DynamoSandbox.exe”*
-
- The NumPy version is: “1.21.4”*
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: DLL load failed while importing _multiarray_umath: The specified module could not be found.
- The NumPy version is: “1.21.4”*
- [’ File “”, line 8, in \n’, ’ File “C:\Users\DELL\anaconda3\envs\Dynamo\Lib\site-packages\numpy\init.py”, line 150, in \n from . import core\n’, ’ File “C:\Users\DELL\anaconda3\envs\Dynamo\Lib\site-packages\numpy\core\init.py”, line 48, in \n raise ImportError(msg)\n’] "*
I am running dynamo core 2.12, any ideas ??

@Ahmed_Ramy did @chuongmep’s link help? 
Thanks for helping Chuong!
Hi Sol ! Thanks for asking. I am really busy this time cause we have other submissions but I’ll try it soon !
Hi,
a workaround to avoid changing the sys.path for each version of Dynamo 
import sys
import clr
import System
import re
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
reDir = System.IO.DirectoryInfo(re.__file__)
path_py3_lib = reDir.Parent.Parent.FullName
sys.path.append(path_py3_lib + r'\Lib\site-packages')
OUT = path_py3_lib
It’s possible to install automatically pip at initialization Python3 engine for next versions of Dynamo ?

I think should support multiple version of python is better.Python 3.10 support debug error very well but some library still not stable

I think it’s not good to mix Python environments, built-in modules are in the directory C:\Users\<USERNAME>\AppData\Local\python-<VERSION>-embed-amd64.
For Python 3.10 I believe only PythonNet 3.00 supports it

I found the step by step description here, seemed a bit cumbersome, so I automated it, at least for a Windows environment. Comments welcome:

if not os.path.isfile(bootstrapPipFilePath):
