Getting an while exporting my trained model by using pickle tool

hi, for data export section in Linear Regression model, i am not able to view pickled saved files.

The files are there but the content is missing. When I try to open the file, I get error message -"the file is not utf-8 encoded. Saving disabled.  See console for more details".It would be very kind of someone, if they kindly help me to fix the error.
