OpenFL installation in windows fails if longpath is not enabled

[ishaileshpant]

• Minor issue related to documentation/pre-requisite step for windows as openfl install via

pip install openfl

fails complaining of LongPath not enabled (which is the case in default in windows)

Using cached openfl-1.6-py3-none-any.whl (11.8 MB)
Installing collected packages: openfl
ERROR: Could not install packages due to an OSError: [Errno 2] No such file or directory: 'C:\\Users\\***\\AppData\\Local\\Packages\\PythonSoftwareFoundation.Python.3.11_qbz5n2kfra8p0\\LocalCache\\local-packages\\Python311\\site-packages\\openfl-tutorials\\experimental\\Vertical_FL\\Workflow_Interface_VFL_Two_Party_Workspace_Creation_from_JupyterNotebook.ipynb'
HINT: This error might have occurred since this system does not have Windows Long Path support enabled. You can find information on how to enable this at https://pip.pypa.io/warnings/enable-long-paths

Solution:

Either use Registry editor or powershell to edit this entry - set to 1 (default 0)

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem]
"LongPathsEnabled"=dword:00000001
