【关闭wandb：yolov5训练报错Wandb wandb.errors.UsageError: api_key not configured (no-tty).】

跑yolov5训练官方代码出现下面的问题第一个方法就是关闭代理网络vpn，直接运行，阻止数据上传。
第二个就是关闭wandb,在yolov5或者是yolov7文件夹找到utils/wandb_logging/wandb_utils.py
将开头代码：

 try:
    import wandb
    from wandb import init, finish
except ImportError:
    wandb = None

改为：

try:
    import wandb
    from wandb import init, finish
except ImportError:
    wandb = None
wandb = None

在这里插入图片描述
就不会报错wandb的了。

第二个方法就是老老实实注册

注册 Wandb 账号：你可以在 Wandb 网站 (https://wandb.ai/) 上创建一个账号并获得 API 密钥。然后，按照说明在你的脚本中配置 API 密钥。

在脚本中配置 API 密钥：如果你已经有 Wandb 账号和 API 密钥，可以直接在脚本中进行配置。找到脚本中类似下面的代码行：

wandb_logger = WandbLogger(opt, Path(opt.save_dir).stem, run_id, data_dict)

在上面的代码之前添加 API 密钥：

wandb.login(key="YOUR_API_KEY")
wandb_logger = WandbLogger(opt, Path(opt.save_dir).stem, run_id, data_dict)

将 “YOUR_API_KEY” 替换为你实际的 API 密钥。

第三个就是禁用 Wandb：如果你不想使用 Wandb 进行实验跟踪，可以通过注释相关的代码行来禁用它。查找以 wandb.init 或 wandb_logger 开头的行，并使用 # 符号将它们注释掉。

例如：

# wandb.init(config=opt, ...)
# ...
# wandb_logger = WandbLogger(opt, Path(opt.save_dir).stem, run_id, data_dict)
