conda安装pynini失败

在部署cosyvoice2时，需要用conda安装pynini，按攻略执行以下命令

conda install -c conda-forge pynini=2.1.5

无法成功，一直保持solving environment：

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

根据这个网页的解决方法尝试后无效Solving environment: failed with initial frozen solve. Retrying with flexible solve的解决方法​​​​​​​​​​​​​​Solving environment: failed with initial frozen solve. Retrying with flexible solve的解决方法https://developer.aliyun.com/article/806916最后去掉版本号后安装成功，查看pynini的版本号：

conda list pynini

显示为2.1.6.post1

但此时安装依赖2.1.5版本的pynini的WeTextProcessing包时仍会报错，于是执行：

pip install WeTextProcessing --no-deps

安装成功
