To solve the warning from sentence_transformers, add 4 configs files.

4 configs file. config.json under 1_Pooling directory as described in modules.json.
With putting those 4 files under the sbert-base-chinese-nli/ , the Warning "WARNING - No sentence-transformers model found with name /Users/peter42/.cache/torch/sentence_transformers/uer_sbert-base-chinese-nli. Creating a new one with MEAN pooling." would be solved.
The reason of Warning is described in the source code of https://github.com/UKPLab/sentence-transformers

If modules.json exsits, standard sentence_transformers load function is called. Or Auto model/Tokenize as huggingface model with mean pooling will be called.
