Hey~ @jeshli , sorry to bother you again, I’ve successfully run your rust-connect-py-ai-to-ic project, but since I didn’t have a tokenizer for transcoding, I created a new canister, but the transcoding has to be done with the files vocab.json and merges.txt, which means that it has to be wasm32-wasi for it to work. But after compiling the tokenizer’s canister to wasm32-wasi, and then generating the did file via candid, I got an error

> Error: unknown import: wasi\_snapshot\_preview1::fd\_filestat\_get has not been defined

I will soon be releasing a new open-source implementation that includes a support for any tokenizer if you can wait.
