Unable to import FlaUI.FlaUI3 library in pythonnet

I am trying to load FlaUI libraries using pythonnet. The code is able to load the FlaUI.UIA3.dll. However, importing FlaUI.UIA3 namespace fails.

Here is my code,

import clr
import sys
dll_path = 'C:\\Users\\amit_tendulkar\\.nuget\\packages\\flaui.core\\3.2.0\\lib\\net45'
dll_path2 = 'C:\\Users\\amit_tendulkar\\.nuget\\packages\\flaui.uia3\\3.2.0\\lib\\net45'
sys.path.append(dll_path)
clr.AddReference('FlaUI.Core')
sys.path.append(dll_path2)
clr.AddReference('FlaUI.UIA3')
from FlaUI.Core import Application
from FlaUI.Core.Conditions import ConditionFactory
from FlaUI.Core.Tools import Retry
from FlaUI.UIA3 import UIA3Automation
from FlaUI.UIA3 import UIA3PropertyLibrary

The error I am getting is below (using command python sample.py),

Traceback (most recent call last):
  File ".\ToadApp.py", line 12, in <module>
    from FlaUI.UIA3 import UIA3Automation
ModuleNotFoundError: No module named 'FlaUI.UIA3'; 'FlaUI' is not a package

If I don't include the FlaUI.UIA3 library then I am able to Launch the application with Application.Launch('software.exe').

Here is the content of my directory containing FlaUI3.UIA3.dll,

C:\Users\amit_tendulkar>dir C:\Users\amit_tendulkar\.nuget\packages\flaui.uia3\3.2.0\lib\net45

Solution

Looks like FlaUI.UIA3.dll has dependency on Interop.UIAutomationClient.dll.

Updating the code to the below solved my issue.

import clr
import sys
flaui_core_path = 'C:\\Users\\amit_tendulkar\\.nuget\\packages\\flaui.core\\3.2.0\\lib\\net45'
flaui_uia3_path = 'C:\\Users\\amit_tendulkar\\.nuget\\packages\\flaui.uia3\\3.2.0\\lib\\net45'
interop_uiautomation_path = 'C:\\Users\\amit_tendulkar\\.nuget\\packages\\interop.uiautomationclient\\10.18362.0\\lib\\net45'
sys.path.append(flaui_core_path)
clr.AddReference('FlaUI.Core')
sys.path.append(interop_uiautomation_path)
clr.AddReference('Interop.UIAutomationClient')
sys.path.append(flaui_uia3_path)
clr.AddReference('FlaUI.UIA3')
from FlaUI.Core import Application
from FlaUI.Core.Conditions import ConditionFactory
from FlaUI.Core.Tools import Retry
from FlaUI.UIA3 import UIA3Automation
from FlaUI.UIA3 import UIA3PropertyLibrary
