TypeError: unsqueeze() missing 1 required positional arguments: "dim"

This error occurs when calling the `unsqueeze()` method without specifying the dimension to unsqueeze along.

For example, if you have a tensor `x` with shape `(3,)` and you want to unsqueeze it to have shape `(1, 3)`, you would call:

x = x.unsqueeze(0)

Here, the `dim` argument is `0`, which specifies to unsqueeze the tensor at the first dimension.

If you forget to specify the `dim` argument, you will get the `TypeError: unsqueeze() missing 1 required positional arguments: "dim"` error.

TypeError: range() missing 1 required positional arguments: "end"

This error occurs when the `range()` function is not provided with the required arguments. The `range()` function requires at least one argument, which is the `end` value of the sequence.

For example, `range(10)` will create a sequence of numbers from 0 to 9, while `range(1, 10)` will create a sequence of numbers from 1 to 9.

Make sure that you provide the required arguments to the `range()` function.

TypeError: forward() missing 2 required positional arguments: 'key' and 'value'

这个错误提示通常发生在使用PyTorch编写自定义的网络模型时，forward()方法缺少必需的位置参数key和value。这个问题可能出现在多种情况下，比如输入数据维度不匹配、未正确初始化模型中的变量、或者传递给forward()方法的参数出错等等。您可以检查这些问题，找到并解决这个错误。如果问题依然存在，您可以参阅PyTorch文档或者寻求相关专业人士的帮助。
