could not broadcast input array from shape(64,) into shape(6,))

这个错误通常是因为你正在尝试将形状不同的数组广播到一起。在 NumPy 中,当你尝试对形状不同的数组进行操作时,NumPy 会尝试将其广播到一个共同的形状,以便能够进行操作。
在这种情况下,你正在尝试将形状为 (64,) 的数组广播到形状为 (6,) 的数组中,这是不可能的。你需要确保你的数组形状相同或可以广播到相同的形状。你可以通过使用 reshape() 函数或者对数组进行切片等方法来改变数组的形状。

could not broadcast input array from shape (12) into shape (16)
This error message indicates that you are trying to perform a broadcasting operation on two NumPy arrays that have incompatible shapes. Specifically, you are trying to broadcast an array with 12 elements into an array with 16 elements, which is not possible.
To fix this error, you need to ensure that the shapes of the arrays are compatible for broadcasting. One way to do this is to reshape the array with 12 elements to have the same shape as the array with 16 elements, or vice versa.
For example, if you have an array with shape (12,) and you want to broadcast it with an array with shape (4, 4), you can reshape the first array to have shape (4, 3) using the `reshape` method:
```python
import numpy as np
a = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12])
b = np.zeros((4, 4))
a_reshaped = a.reshape((4, 3))
result = a_reshaped + b
```
Alternatively, you could reshape the second array to have shape (12,) using the `flatten` method:
```python
import numpy as np
a = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12])
b = np.zeros((4, 4))
b_flat = b.flatten()
result = a + b_flat
```
Both of these approaches will ensure that the arrays have compatible shapes for broadcasting.
上面的代码报错了。could not broadcast input array from shape(64,) into shape(6,))
这个错误信息提示你的代码中涉及到了数组的形状(shape)不匹配的问题。具体来说,你在将一个形状为(64,)的数组广播(broadcast)成形状为(6,)的数组时出现了问题。
广播是一种 NumPy 中的操作,它允许在不同形状的数组之间进行运算。但是,在进行广播时,NumPy 会按照一定的规则自动调整数组的形状,使得它们能够匹配。
根据你的错误信息,可以看出,在你的代码中有一个数组的形状是(64,),而你试图将它广播成形状为(6,)的数组,但是这种广播是无法进行的,因为这两个形状不匹配。
要解决这个问题,你需要检查你的代码中哪些地方涉及到了数组的形状,并且确保它们的形状是匹配的。你可以使用 NumPy 的 reshape() 函数来改变数组的形状,或者使用其他的数组操作函数来实现你的需求。
