Try updating `gpt index` to latest

Thanks! updating worked for this error. another basic question, i'm now getting the error "TypeError: object.init() takes exactly one argument (the instance to initialize)" when I follow the code on https://llamahub.ai/l/file. Any advice on this? 🙂

@qianminhu can you send a screenshot of your code snippet?

Just tried this out and it seemed to work for me

ah just realized there's a typo in the readme! There should be quotes around the SimpleDirectoryReader. See my screenshot above. Will fix
