@szha In gluon.distribution, floating number of very small value are often clipped to a minimum value to avoid numerical issue in downstream tasks, e.g. https://github.com/apache/incubator-mxnet/blob/master/python/mxnet/gluon/probability/distributions/utils.py#L164-L172
The clip is very necessary, otherwise tons of NaN would come up when very small value are fed into OPs like `log`. -- You are receiving this because you were mentioned. Reply to this email directly or view it on GitHub: https://github.com/apache/incubator-mxnet/issues/19361#issuecomment-713305611
