error: casting to type 'half' is not allowed on 7900xt

[michbogos]

When I run the conversation.py example, it downloads the tensors, but fails on the line toks, user_delim, resp_delim, start_pos, outputted = llama_prepare(llama, args.llama_temperature, args.llama_pre_prompt_path) and gives the following error:

raise RuntimeError(f"OpenCL Compile Error\n\n{ctypes.string_at(mstr, size=log_size.value).decode()}")
RuntimeError: OpenCL Compile Error

I'm using Linux Mint 21.2 with ROCm 5.7.2 version drivers. I also have integrated Radeon graphics and a 7900xt.

[michbogos]

Fixed in newer version of tinygrad.

[b1tg]

Still get this error on commit f018a55, which version solved your issue @michbogos

[okias]

I can confirm this issue on iris+rusticl with tiny-llama with today master.
