[GitHub] [incubator-mxnet] dibgerge opened a new issue #19720: `Distribution` repr fails if cached_property not initialized
dibgerge opened a new issue #19720:
URL: https://github.com/apache/incubator-mxnet/issues/19720
## Description
When defining a `Categorical` distribution using `logit` and then trying to display the distribution in the repl, it failed due to `KeyError: prob`. This error will happen to any distribution which contains `cached_properties` as part of its arguments declared `arg_contraints`.
### Error Message
```python
~/workplace/incubator-mxnet/python/mxnet/gluon/probability/distributions/distribution.py in __repr__(self)
181 if 'symbol' not in mode.__name__:
182 for k, _ in self.arg_constraints.items():
--> 183 v = self.__dict__[k]
184 if isinstance(v, Number):
185 shape_v = ()
KeyError: 'prob'
```
## To Reproduce
```python
from mxnet import np
from mxnet.gluon.probability import Categorical
a = np.array([1, 2, 3])
dist = Categorical(1, logit=a)
>>> dist
#KeyError
```
## What have you tried to solve it?
Simply calling the undeclared `cached_property` first solves it. That is:
```python
a = np.array([1, 2, 3])
dist = Categorical(1, logit=a)
dist.prob
>>> dist
# Categorical(prob: size (3,), logit: size (3,), F: mxnet.ndarray, event_dim: 0)
# ...Works
```
