Motivation
I noticed that the current lmdeploy does not use tensor parallelism for the embedding layer and lm_head, yet they consume nearly as much GPU memory as the linear layers.Maybe This PR adds support for tensor parallelism in the embedding layer.
Modification
Perhaps TP (tensor parallelism) for embedding and lm_head could be enabled by default in lmdeploy, or a new args could be added to let users control whether to enable or disable embedding parallelism？
