self-supervised pretraining(wav2vec 2.0/data2vec) for wenet

[Emiyassstar]

1.support self-supervised pretraining using wav2vec 2.0/data2vec method
2.add ssl recipe in librispeech/ssl
3.add ssl recipe in aishell/ssl

cool!

我尝试复现这个例子，使用https://huggingface.co/emiyasstar/ch-w2v-conformer 这个预训练模型，报错如下：
Traceback (most recent call last):
File "wenet/bin/train.py", line 322, in
main()
File "wenet/bin/train.py", line 234, in main
infos = load_trained_modules(model, args)
File "/home/wenet_ssl/wenet/utils/checkpoint.py", line 95, in load_trained_modules
model.load_state_dict(main_state_dict)
File "/home/miniconda3/envs/wenet/lib/python3.8/site-packages/torch/nn/modules/module.py", line 1482, in load_state_dict
raise RuntimeError('Error(s) in loading state_dict for {}:\n\t{}'.format(
RuntimeError: Error(s) in loading state_dict for Wav2vec2Model:
Unexpected key(s) in state_dict: "encoder.embed.linear.weight", "encoder.embed.linear.bias".
size mismatch for encoder.embed.conv.2.weight: copying a param with shape torch.Size([512, 512, 5, 5]) from checkpoint, the shape in current model is torch.Size([512, 512, 3, 3]).
我该如何修改？ 希望得到您的回复。

ch-w2v-conformer使用的是6倍降采样模型，并且去除了预训练部分的训练参数以兼容master分支代码，你可以配合我们放出的 openasr recipe 里面提供的配置文件去加载模型

感谢您的回复，https://github.com/wenet-e2e/wenet/blob/1269a6e5bbec440302e934f243f623baeebf2758/examples/aishell/s0_ssl/README.md 提到的使用fbank作为特征输入所训练的w2v-conformer 模型开源了吗？

请问有wav2vec的预训练模型吗
