About "INITIAL PCA + PRUNE" error

[ChuckGithub]

Hi,
when i run this command 'lsfm -i input_data -o output_data', I met some problems:

Input directory provided - scanning for importable meshes
Found 5 input meshes under: input_data
Resuming processing for output directory: D:\lsfm\lsfm\output_data
Current meshes are the same as the meshes in the input dir - resuming
Outputting results to D:\lsfm\lsfm\output_data
