[Errno 22] Invalid argument

[buran]

as you run it now, it looks for the csv file in your CWD - C:\Python27\
You need to supply the full path as you do with the Main.py or
run the script from C:/Users/asafb/PycharmProjects/Sanity_HB_RR_from_Saved_Pos/
or add code that extracts the path of the script and add it to the argument to get the full path
