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.

I'm assuming this is from the Postgres log.
Best guess is the table name in the database is mixed case and needs to
be double quoted in the command to preserve the casing.
See:
https://www.postgresql.org/docs/current/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS <https://www.postgresql.org/docs/current/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS>
for why.
