when i run the scripts code, I alwys got the following:No API key provided. You can set your API key in code using 'openai.api_key = <API-KEY>', or you can set the environment variable OPENAI_API_KEY=<API-KEY>). If your API key is stored in a file, you can point the openai module at it with 'openai.api_key_path = <PATH>'. #29
but Actually I already set the enviroment variable and echo$OPENAI_API_KEY output the right value sk-XXXXXXXXXXXXXXXXXXX
