_choose_dispatcher() missing 1 required positional argument: 'choices'

这个错误通常是因为 `_choose_dispatcher()` 函数的调用缺少参数 `choices`,请检查函数调用并确保传递了正确的参数。以下是一个示例:
```
def _choose_dispatcher(choices):
# 函数的实现代码...
my_choices = ['A', 'B', 'C']
result = _choose_dispatcher(my_choices)
```
在上面的示例中,`_choose_dispatcher()` 函数需要一个参数 `choices`,并将其作为列表传递给了函数。如果您没有传递这个参数或者传递的参数不是列表类型,就会出现这个错误。请检查函数调用并确保传递了正确的参数。

_mean_dispatcher() missing 1 required positional argument: 'a'
This error occurs when the function `_mean_dispatcher()` is called without passing the required argument `a`.
For example, if the function is defined as follows:
```
def _mean_dispatcher(a):
if isinstance(a, (list, tuple)):
return mean_list(a)
elif isinstance(a, dict):
return mean_dict(a)
else:
raise TypeError("Unsupported type")
```
And it is called without passing `a`:
```
_mean_dispatcher()
```
Then the error message will be:
```
TypeError: _mean_dispatcher() missing 1 required positional argument: 'a'
```
To fix this error, you need to make sure to pass the required argument `a` when calling the function. For example:
```
_mean_dispatcher([1, 2, 3])
```
This will call the `mean_list()` function and return the mean of the list `[1, 2, 3]`.
TypeError: _savetxt_dispatcher() missing 1 required positional argument: 'X'
这个错误通常是因为调用 `numpy.savetxt()` 函数时参数传递错误导致的。
请检查你调用 `numpy.savetxt()` 函数时的参数是否正确,确保传递了正确的参数数量和类型。
例如,如果你使用了以下代码:
```python
import numpy as np
data = np.array([[1, 2], [3, 4]])
np.savetxt('data.txt')
```
那么你会遇到 `TypeError: _savetxt_dispatcher() missing 1 required positional argument: 'X'` 错误,因为在调用 `np.savetxt()` 函数时,你没有传递 `X` 参数,即要保存的数据。应该修改为:
```python
import numpy as np
data = np.array([[1, 2], [3, 4]])
np.savetxt('data.txt', data)
```
这样就可以成功保存数据了。
