你好，我在训练模型时遇到了这个问题，请问如何解决

[Ye-jc]

python scripts/train.py +experiment=GaussianLSS

Seed set to 2025
Error executing job with overrides: ['+experiment=GaussianLSS']
Error locating target 'GaussianLSS.model.GaussianLSS.GaussianLSS', set env var HYDRA_FULL_ERROR=1 to see chained exception.
full_key: model

Set the environment variable HYDRA_FULL_ERROR=1 for a complete stack trace.

尝试修改指令后HYDRA_FULL_ERROR=1 python scripts/train.py +experiment=GaussianLSS
报错

@Ye-jc 看起來是conda env沒裝好，可以重裝看看。
