在DataLoader里,除了上面提到的shuffle参数和batch_size参数以外,还有一个非常重要的传入参数collate_fn,这个参数传入的是一个函数,这个函数主要是对每个batch进行处理,最终输出一个batch的返回值,换句话说collate_fn函数的返回值,就是遍历DataLoader的时候每个“batch”的返回值了(类似于上面例子中的二维tensor)。下面我...

这可以通过在collate_fn函数中添加打印语句来实现。 5. 重新运行代码,验证问题是否已解决 在修改代码后,重新运行代码以验证问题是否已解决。如果仍然出现错误,请检查修改是否正确,并继续调试。 通过以上步骤,你应该能够解决RuntimeError: each element in list of batch should be of equal size这个错误。如果问题...
