RuntimeError: shape '[5, 1, 100]' is invalid for input of size 300

这个错误提示表明你的输入张量的大小不符合要求。根据错误信息,你的输入张量的大小应该是300,而你尝试将其变换为形状为`(5, 1, 100)`的张量。
可能的原因是你的输入张量的大小不是300,而是其他的值。请检查你的输入张量的大小是否正确,并确保它与你尝试变换的目标形状相匹配。另外,也请确保你正在使用正确的函数和参数进行形状变换。

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.
