TypeError: unsqueeze() missing 1 required positional arguments: "dim"
时间: 2023-09-21 12:11:24 浏览: 66
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: circle() missing 1 required positional argument: 'param1'
这个错误通常是因为在调用函数时,没有传递足够的参数。在这种情况下,函数期望接收一个参数,但是在调用函数时没有传递任何参数。这个错误信息告诉我们函数circle()缺少一个必需的位置参数param1。
以下是一些可能导致这个错误的示例代码:
```python
# 示例1
def circle(param1, param2):
print("The circle has a radius of", param1, "and a color of", param2)
circle() # 报错:TypeError: circle() missing 2 required positional arguments: 'param1' and 'param2'
# 示例2
def circle(param1):
print("The circle has a radius of", param1)
circle() # 报错:TypeError: circle() missing 1 required positional argument: 'param1'
```
在这些示例中,函数circle()需要一个参数,但是在调用函数时没有传递任何参数,导致了TypeError错误。
