[GitHub] [incubator-mxnet] vietspaceanh opened a new issue #17307: NDArray
does not have `std()` method
vietspaceanh opened a new issue #17307: NDArray does not have `std()` method
URL: https://github.com/apache/incubator-mxnet/issues/17307
Although `ndarray.mean()` exists, I cannot find the standard deviation method for `NDArray'.
Example:
```python
from mxnet import nd
a = nd.random.randn(3,3)
a.std()
```
```
AttributeError: 'NDArray' object has no attribute 'std'
```

I don't see this option in mxnet 1.5.1.

@vietspaceanh In case it helps your usecase, there is:
`import mxnet.numpy as np`
`a = np.random.randn(3,3)`
`np.std(a)`
array(0.8727266)
