D-Roberts opened a new issue #17529: np.random.gamma(1,0) and np.random.gamma(0,0) hang URL: https://github.com/apache/incubator-mxnet/issues/17529 ## Description On my system, numpy.random.gamma(1,0) and numpy.random.gamma(0,0) do not produce a value or an error, but just hang. In original numpy, they generate 0.0. ### Error Message No error message. ## To Reproduce ### Steps to reproduce 1. build mxnet from source 2. import mxnet as mx 3. run: mx.numpy.random.gamma(1,0) mx.numpy.random.gamma(0,0) ## Environment ``` ----------Python Info---------- Version : 3.7.6 Compiler : Clang 4.0.1 (tags/RELEASE_401/final) Build : ('default', 'Jan 8 2020 13:42:34') Arch : ('64bit', '') ------------Pip Info----------- Version : 20.0.2 Directory : /Users/denisaroberts/anaconda3/lib/python3.7/site-packages/pip ----------MXNet Info----------- Version : 1.6.0 Directory : /Users/denisaroberts/workspace/incubator-mxnet/python/mxnet Num GPUs : 0 Hashtag not found.
