它会根据你是否传入weights来决定是否加载预训练参数 这个函数还带有装饰器@register_model(),表示它是一个官方注册的模型构建函数,可供torchvision.models模块使用;@handle_legacy_interface 装饰器是为了兼容旧接口参数命名方式。也就是说,为了向后兼容旧代码,那些还在用pretrained=True的人,torchvision用了这个装饰器来...

函数内第一行和最后一行的HANDLE_TH_ERRORS和END_HANDLE_TH_ERRORS,是在文件 torch/csrc/Exceptions.h 中定义的宏,具体地,分别在第 41 行和第 114 行被定义。这部分代码主要是通过函数PyArg_ParseTupleAndKeywords对输入的参数重新解析并赋值给新定义的变量tensors...
PyTorch stands out as an open-source library for machine learning, characterized by its user-friendly Pythonic interface that enhances debugging and customization. Its dynamic computation graph and flexible architecture make it particularly advantageous for research and prototyping. However, compared to Tens...
