Python错误：需要以下参数：experimentname

Question

我是Python和PyTorch环境的初学者。我正在GitHub上执行程序。 我得到以下错误：

usage: main.py [-h] [--self_host SELF_HOST] [--cpu] [--port PORT]
               [--server_port SERVER_PORT] [--config CONFIG]
               [--devices_per_trial DEVICES_PER_TRIAL] [--dataroot DATAROOT]
               [--s3 S3] [--logroot LOGROOT] [--seed SEED]
               [--num_eigenthings NUM_EIGENTHINGS] [--batch_size BATCH_SIZE]
               [--eval_batch_size EVAL_BATCH_SIZE] [--momentum MOMENTUM]
               [--num_steps NUM_STEPS] [--max_samples MAX_SAMPLES] [--cuda]
               [--full_dataset] [--fname FNAME] [--mode {power_iter,lanczos}]
               experimentname
main.py: error: the following arguments are required: experimentname
An exception has occurred, use %tb to see the full traceback. 

SystemExit: 2

在%tb时，我得到以下详细信息：

Traceback (most recent call last):

    skeletor.execute(main)

  File "/home/ajinkya/miniconda3/lib/python3.8/argparse.py", line 2508, in exit
    _sys.exit(status)

SystemExit: 2

请帮忙消除这个错误。提前谢谢

您的CLI似乎与从^{}公开的CLI不同。无论如何，所有以为前缀的选项都是选项（如 self_host， cpu，…）。唯一（必需）的位置参数是experimentname，因此在调用main.py时需要提供它

最低限度的电话是：

python main.py my_experiment
