AttributeError: 'CrossEntropyLoss' object has no attribute 'label_smoothing'

引用中提到的错误代码是错误的，因为在定义CrossEntropyLoss_func函数时，直接返回了nn.CrossEntropyLoss()，而没有对其参数进行处理。因此，在调用CrossEntropyLoss_func函数时，会直接调用CrossEntropyLoss的backward方法，而不是对返回值使用backward方法。这导致了AttributeError: 'CrossEntropyLoss' object has no attribute 'label_smoothing'的错误。

正确的代码应该是根据需要对nn.CrossEntropyLoss进行参数设置，然后再返回相应的损失函数对象。例如，如果需要使用label_smoothing参数，可以将其作为参数传递给nn.CrossEntropyLoss函数，然后再返回损失函数对象。可以根据实际需要对代码进行修改，确保在调用损失函数对象时不出现AttributeError: 'CrossEntropyLoss' object has no attribute 'label_smoothing'的错误。<em>1</em><em>2</em><em>3</em>
