fairseq - how can i use fairseq2 in conda envirionment for using sonar and lcm from meta? - Stack Overflow

`I would like to install fairseq2 for using SONAR and LCM(Large Concept Model) from Meta for my personal research interest. I think I just followed the instruction from them(#installing) (#variants). I installed pytorch==2.5.1 and cu118 under python==3.11.11.

I think it should work when I install above version of packages with sonar and sonar-space, but it doesn't work. (Also i installed conda-forge libsndfile==1.0.31)

I could never know what the problem is and how can i solve this shit.

Do you guys know how to solve this issue?

Below message is after i activate the code like this:

from sonar.inference_pipelines.text import TextToEmbeddingModelPipeline
t2vec_model = TextToEmbeddingModelPipeline(encoder="text_sonar_basic_encoder",
                                             tokenizer="text_sonar_basic_encoder")
