RuntimeError: shape '[1]' is invalid for input of size 2

这个错误通常发生在输入数据的维度不匹配时。在PyTorch中,张量的维度应该是一个整数的元组,用于描述张量的形状。这个错误信息的意思是,你尝试将一个大小为2的张量转换成形状为[1]的张量,这是不允许的。可能你的代码中有一个维度的错误,或者在数据处理中出现了错误。你需要检查一下你的代码,确保输入的张量的形状和你的模型的输入形状匹配。

RuntimeError: shape [-1, 784] is invalid for input of size 131072
This error message indicates that the input tensor has a shape of [-1, 784], which means that the first dimension is unknown and the second dimension is 784. However, the size of the input tensor is 131,072, which is incompatible with the specified shape.
To fix this error, you should check the input data and make sure that it has the correct shape and size. It's possible that the input data has been incorrectly formatted or preprocessed, or that the model architecture is not compatible with the input data.
You can also try adjusting the shape of the input tensor to match the size of the input data. For example, you might need to reshape the input data to have a different number of dimensions or a different size for the first dimension. Alternatively, you might need to modify the model architecture to accept a different input shape.
Overall, the best approach to fixing this error will depend on the specific details of your model and input data.
RuntimeError: shape '[8]' is invalid for input of size 16
这个错误通常发生在你试图将一个形状为[8]的张量输入到一个期望输入大小为16的操作中。这可能是因为你的代码中存在一些错误,例如不正确地计算了张量的形状或者使用了错误的参数。
要解决这个问题,你需要检查你的代码中与输入张量相关的所有操作,确保它们都正确地计算了张量的形状,并且使用了正确的参数。你还可以尝试打印出张量的形状,以便更好地理解问题所在。如果问题仍然存在,你可以考虑使用调试工具来帮助你定位问题。
