xidulu opened a new issue #17363: Random generator testing not working correctly,
URL: https://github.com/apache/incubator-mxnet/issues/17363
 
 
   ## Description
   Changing the `ss.norm.ppf` to `ss.logistic.ppf` or `ss.gumbel_r.ppf` will not affect the result of the test, which is clearly problematic.
   
   https://github.com/apache/incubator-mxnet/blob/master/tests/python/unittest/test_random.py#L614
   
   To reproduce:
     1.  Replace the `ss.norm.ppf` in line 614 in test_random.py with `ss.gumbel_r.ppf`
     2. Run `MXNET_ENGINE_TYPE=NaiveEngine nosetests -s --verbose tests/python/unittest/test_random.py:test_normal_generator`
   
   the output on my device was:
   ```
   [INFO] Setting module np/mx/python random seeds, use MXNET_MODULE_SEED=1198992244 to reproduce.
