## To Reproduce
(If you developed your own code, please provide a short script that
reproduces the error. For existing examples, please provide link.)
```python
from mxnet import np, npx
npx.set_np()
np.apply_along_axis(lambda x: x.mean(), axis=1, arr=data)
```
### Steps to reproduce
(Paste the commands you ran that produced the error.)
1. open terminal
2. get into ipython console
3. run code written above
## What have you tried to solve it?
1. I've tries origin numpy method, codes written below
```python
import numpy as np
data = np.array([[1,2,3.], [4.,5.,6]])
print(np.apply_along_axis(lambda x: x.mean(), axis=1, arr=data))
```
2. Codes just worked.
