some time faced below issue:
thread 'main' panicked at src/main.rs:579:14:
The read bytes are not valid UTF-8: Error { kind: InvalidData, message: "stream did not contain valid UTF-8" }
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

below is my command:
wasmedge --dir .:. --nn-preload default:GGML:CPU:MiniCPM-2B-dpo-q4km-gguf.gguf llama-chat.wasm -g 0
