The default value for layer_sizes is [1000] in the parameter description, while in the method signature, it is [100].This inconsistency could potentially confuse users who rely on the documentation to understand the default behavior of the DTNNGather class.

Description

Fix #3854

The default value for layer_sizes is [1000] in the parameter description, while in the method signature, it is [100].This inconsistency could potentially confuse users who rely on the documentation to understand the default behavior of the DTNNGather class.To resolve this discrepancy, we need to ensure that both the parameter description and the method signature reflect the same default value for layer_sizes.
