`--ckpt_url`，`--data_url`, `--multi_date_url`等参数无定义导致的报错问题 ``` ##### 2, 多卡训练任务如何只让数据集只拷贝一次 使用缓存文件和local_rank%8作为判断，若第0卡拷贝完成，则其它卡不拷贝，并在第0卡拷贝数据完成后才执行之后的代码，具体可参考示例中[train_multi_card.py](./train_multi_card.py)的代码注释 ``` if local_rank%8==0: 这里省略下载数据的代码... f = open("/cache/download_input.txt", 'w') f.close() try: if os.path.exists("/cache/download_input.txt"): print("download_input succeed") except Exception as e: print("download_input failed") while not os.path.exists("/cache/download_input.txt"): time.sleep(1) ``` ##### 3, 公共库[c2net](https://openi.pcl.ac.cn/OpenIOSSG/c2net-pypi)高级用法： 主要使用的方法有以下几个： ``` from c2net.context import prepare, upload_output, moxing_helper prepare() 准备数据集，模型，输出路径 upload_output() 将训练镜像的输出结果拷贝回启智平台 moxing_helper.obs_copy_file(string,string) 通过mox拷贝文件 moxing_helper.obs_copy_folder(string,string) 通过mox拷贝文件夹 ``` ## 对于示例代码有任何问题，欢迎在本项目中提issue。 openi_cloudbrain_example/npu_mnist_example/config.py000066400000000000000000000022201472322360600234540ustar00rootroot00000000000000# Copyright 2020 Huawei Technologies
