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.
