Connect to the database with psql and look at the table name. I'm
betting it is not image_classification_master. Instead some mixed or all
upper case version of the name.
I don't use PowerShell or Windows for that matter these days so I can't
be of much use on the script. I do suspect you will need to some
escaping to get the table name properly quoted in the script. To work
through this you need to try what I call the crawl/walk/run process. In
this case that is:
1) Crawl. Connect using psql and run the \copy in it with hard coded values.
2) Walk. Use psql with the -c argument and supply the command again with
hard coded values
3) Run. Then use PowerShell and do the variable substitution.
