[GitHub] [incubator-mxnet] kshitij12345 opened a new issue #17342: [bug]
Indexed Assignment Incorrect
kshitij12345 opened a new issue #17342: [bug] Indexed Assignment Incorrect
URL: https://github.com/apache/incubator-mxnet/issues/17342
## Description
Incorrect output when assigning with mask_array
## To Reproduce
```python
import mxnet as mx
import numpy as np
def test_replace(array_constructor):
array = [[0.0, 2]]
x = array_constructor(array)
zero_mask = x == 0.0
print(zero_mask)
x[zero_mask] = 1e-6
print(x)
test_replace(mx.nd.array)
print('*' * 8)
test_replace(np.array)
```
## Output
```
[[1. 0.]]
<NDArray 1x2 @cpu(0)>
[[1.e-06 1.e-06]]
<NDArray 1x2 @cpu(0)>
********
[[ True False]]
[[1.e-06 2.e+00]]
```

@haojin2
Noted.
However shouldn't there be some sort of deprecation warning or anything. Cause right now it silently computes the incorrect result.

@kshitij12345 This has been addressed in the new `np` module:
```python
from mxnet import np, npx
npx.set_np()
import numpy as onp
def test_replace(array_constructor):
array = [[0.0, 2]]
x = array_constructor(array)
zero_mask = x == 0.0
print(zero_mask)
x[zero_mask] = 1e-6
print(x)
test_replace(np.array)
print('*' * 8)
test_replace(onp.array)
```
running this on the latest master:
```
[[ True False]]
[[1.e-06 2.e+00]]
********
[[ True False]]
[[1.e-06 2.e+00]]
```
