Limitations and known issues
►Spaces in ink file paths in training or test list files causes error
► Problem statement
The runshaperec.exe reports error if the file paths mentioned in the list files for training or testing contain spaces.
► Workaround
Do not use directory or files names with spaces in them, or (for Windows platforms) use the DOS path instead (e.g. for C:\program files, use "C:\progra~1").
Backward Compatibility
Version 2.2 of core toolkit does not maintain backward compatibility with previous releases of core toolkit.
