[GitHub] [incubator-mxnet] canerturkmen opened a new issue #16049: Gluon
HybridBlock instantiation with params compares initializers
canerturkmen opened a new issue #16049: Gluon HybridBlock instantiation with params compares initializers
URL: https://github.com/apache/incubator-mxnet/issues/16049
## Description
HybridBlocks do not initialize with params when parameter initializers are explicitly given, and two initializers don't match (by reference).

from mxnet import gluon
class MyBlock(gluon.HybridBlock):
def __init__(self, **kwargs):
super().__init__(**kwargs)
with self.name_scope():
self.some_param = self.params.get(

bl.initialize()
