ID 579394 - The pxr module fails to import * due to missing UsdAbc module in Nuke

Problem summary
An error is given when importing pxr via Python in Nuke.
 
Customer reported version
Nuke 15.0v4
 
Customer reported platform
Windows 10
 
Steps to reproduce
1) In Nuke, open the Script Editor.
2) Run either command: from pxr import * or from pxr import UsdAbc
3) Observe the results in the Script Editor.
 
Expected behavior
The USD library should be available when importing from pxr.
 
Actual behavior
The USD library is missing and provides an error for ""ImportError: DLL load failed while importing _usdAbc: The specified module could not be found" when running the command from pxr import * or from pxr import UsdAbc
 
Workaround
Ingesting a USD asset as a ReadGeo on the Node Graph allows the import to work as expected. Also, adding the code snippet below to the init.py allows the import to happen without error:

def pxrUSDWorkaround():    someUSD = "path/to/file.usd"    tmp = nuke.createNode("ReadGeo2")    tmp["file"].setValue(someUSD)    from pxr import UsdAbc    nuke.delete(tmp)nuke.addOnCreate(pxrUSDWorkaround, nodeClass="Root")
