eric-haibin-lin opened a new issue #15225: nd.random is not really random
URL: https://github.com/apache/incubator-mxnet/issues/15225
 
 
   numpy random module uses a different seed each time program starts: 
   ```
   python
   >>> import numpy as np; np.random.randint(10)
   4
   ```
   ```
   [ec2-user@ip-172-31-10-195 bert]$ python
   Python 2.7.16 (default, Mar 18 2019, 18:38:44)
   [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] on linux2
   >>> import numpy as np; np.random.randint(10)
   >>> 1
   ```
   
   however, mxnet has a fixed random seed:
   ```
   Type "help", "copyright", "credits" or "license" for more information.
   >>> import mxnet as mx; mx.nd.random.randint(low=0, high=10)
   
   [1]
   <NDArray 1 @cpu(0)>
   ```
   ```
   Type "help", "copyright", "credits" or "license" for more information.
   >>> import mxnet as mx; mx.nd.random.randint(low=0, high=10)
   
   [1]
   <NDArray 1 @cpu(0)>
   ```
   @astonzhang also find this behavior confusing for d2l readers. We should fix it for our numpy compatible feature.
