The error of compressing the model finetuned by DPA-3

[Zhou-tao-USTC]

命令行如下，在尝试对DPA-3微调后的模型进行压缩时遇到报错：

To get the best performance, it is recommended to adjust the number of threads by setting the environment variables OMP_NUM_THREADS, DP_INTRA_OP_PARALLELISM_THREADS, and DP_INTER_OP_PARALLELISM_THREADS. See https://deepmd.rtfd.io/parallelism/ for more information.
