Code running error #89

Closed dreamerforwuyang closed 1 month ago

When I set the etth1 data format and find a running error, how can I modify it

    This probably means that you are not using fork to start your
    child processes and you have forgotten to use the proper idiom
    in the main module:

        if __name__ == '__main__':
            freeze_support()
            ...

    The "freeze_support()" line can be omitted if the program
    is not going to be frozen to produce an executable.

Hi, it looks like this issue is caused by running the process on your local CPU. If you are running it locally on a CPU, you need to set num_workers to 0 and use_gpu parameter to False. You can try running it again with these settings. However, please note that since the base model uses LLaMA2, which is an LLM, it is recommended to use 8 A100 GPUs for execution.
