could not broadcast input array from shape (61,10) into shape (61)

这个错误通常是因为你试图将一个形状为(61,10)的数组广播到形状为(61)的数组。这可能是因为你正在使用了不兼容的数组操作。
你可以检查你的代码中是否有这样的操作。另外,你可以检查你的输入数据的形状是否正确,以确保它们与你的期望形状相匹配。如果你遇到了这个问题,你可以尝试重新构造你的数据,或者修改你的操作,以使它们与你的数据形状相匹配。

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.
could not broadcast input array from shape (10,) into shape (21,)
这个错误通常出现在使用numpy数组时,尝试将一个形状为(10,)的数组广播到一个形状为(21,)的数组时。
要解决这个问题,你需要确保你的数组形状匹配。可以使用numpy的reshape函数来改变数组的形状,或者使用numpy的concatenate函数将两个数组合并。
例如,如果你想将一个形状为(10,)的数组a广播到一个形状为(21,)的数组b,你可以这样做:
```
import numpy as np
a = np.zeros((10,))
b = np.ones((21,))
# 使用reshape函数改变a的形状
a_reshaped = a.reshape((1, 10))
# 使用concatenate函数将a和b合并
c = np.concatenate((a_reshaped, b[None, :10]), axis=0)
print(c.shape) # 输出(21, 10)
```
在这个例子中,我们首先使用reshape函数将a的形状从(10,)改变为(1, 10),然后使用concatenate函数将a和b的前10个元素合并在一起。最终得到的数组c的形状为(21, 10)。
