the program prints "Info: could not find files for the given pattern" but correctly parses PDFs to texts and trains models from texts

After I entered "topicexplorer init FILENAME", for each of the three files inside the folder, the program says that "could not find files for the given pattern", but later it correctly parses PDFs to text files and train models from those texts.
Also, line 403 in init.py "args.corpus_print_name = prompt("Corpus Name", default=args.corpus_name)" causes the program to break in windows.
