I am learning gpt fine-tuning
I successfully ran this command: pip install --upgrade openai
I couldn't run this command: export OPENAI_API_KEY="sk-xxxxxxxxxxxxxx"
Error: export : The term 'export' is not recognized as the name of a cmdlet, function, script file, or operable program.
So I ran this command instead: set OPENAI_API_KEY="sk-xxxxxxxxxxxxxx"
Also ran Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope CurrentUser
Now I'm trying to run openai tools fine_tunes.prepare_data -f C:\Users.....fine-tune-upload.xlsx
But it shows: error: unknown command 'tools'
Any idea? Please explain in beginner language!
