non-broadcastable output operand with shape (121,1) doesn't match the broadcast shape (121,11)

这个错误通常意味着你正在尝试将一个形状为(121,1)的数组与一个形状为(121,11)的数组进行广播操作,但是它们的形状不兼容。在广播过程中,NumPy会尝试将较小的数组沿着特定的轴复制,以便与较大的数组的形状匹配。但是,如果无法匹配,则会出现此错误。
解决此错误的方法是检查你的代码,确保你正在使用的数组具有相同的形状或相容的形状。可以使用`numpy.reshape()`函数来改变数组的形状。另外,也可以使用`numpy.newaxis`在必要时添加额外的维度来使数组的形状匹配。

non-broadcastable output operand with shape (50,1) doesn t match the broadcast shape (50,5)
This error occurs when you are trying to perform a broadcast operation on two arrays with incompatible shapes. In this case, the output operand has a shape of (50,1) which means it has 50 rows and 1 column, while the broadcast shape has a shape of (50,5) which means it has 50 rows and 5 columns.
Broadcasting is a way to perform operations on arrays with different shapes by stretching or duplicating one or more of the arrays to match the shape of the other. However, in this case, the arrays cannot be broadcasted because they have different numbers of columns.
To fix this error, you need to reshape one of the arrays to have the same number of columns as the other. You can use the numpy.reshape() function to do this. For example, if you want to reshape the output operand to have the same shape as the broadcast shape, you can use the following code:
```
import numpy as np
# create two arrays with incompatible shapes
a = np.ones((50,1))
b = np.ones((50,5))
# reshape the output operand to have the same shape as the broadcast shape
a = np.reshape(a, (50,5))
# perform the broadcast operation
c = a + b
```
This code will reshape the output operand to have the same shape as the broadcast shape, and then perform the broadcast operation without any errors.
non-broadcastable output operand with shape (10,1) doesn't match the broadcast shape (10,29)
This error message suggests that there is an issue with the shapes of the arrays being used in a broadcast operation. Specifically, there is a mismatch between the shape of the output array and the shape that is being broadcasted.
In this case, the output array has a shape of (10,1), which means it has 10 rows and 1 column. However, the shape that is being broadcasted has a shape of (10,29), which means it has 10 rows and 29 columns. These shapes are not compatible because the number of columns in the output array does not match the number of columns being broadcasted.
To resolve this error, you should check the arrays being used in the broadcast operation and make sure they have compatible shapes. You may need to reshape one or both of the arrays to ensure they have the same number of columns. Alternatively, you may need to adjust the broadcasting axis to match the shape of the output array.
