### WenetSpeech char-based training results (Non-streaming and streaming) on zipformer model
This is the [pull request](https://github.com/k2-fsa/icefall/pull/1130) in icefall.
#### Non-streaming
Best results (num of params : ~76M):
Type | Greedy(dev & net & meeting) | Beam search(dev & net & meeting) |  
-- | -- | -- | --
Non-streaming | 7.36 & 7.65 & 12.43 | 7.32 & 7.61 & 12.35 | --epoch=12
The training command:
```
./zipformer/train.py \
--world-size 6 \
--num-epochs 12 \
--use-fp16 1 \
--max-duration 450 \
--training-subset L \
--lr-epochs 1.5 \
--context-size 2 \
--exp-dir zipformer/exp_L_context_2 \
--causal 0 \
--num-workers 8
```
Listed best results for each epoch below:
Epoch | Greedy search(dev & net & meeting) | Modified beam search(dev & net & meeting) |  
-- | -- | -- | --
