seamless_communication require fairseq2n == 0.2.0

I try to install seamless_communcation on a man intel. I've followed all the instructions to install fairseg2 but when I try to install seamless_communcation I receive the Error:
ERROR: Could not find a version that satisfies the requirement fairseq2n==0.2.0 (from fairseq2) (from versions: none)
ERROR: No matching distribution found for fairseq2n==0.2.0

doing pip show fairseq2n the result is:

How can I install version 0.2.0?
