Dear professor:
         I run the example ''./cado-nfs.py 100000000000000000039 -dlp -ell 164354743277891 -gfpext 2'' in params.p2dd20.
get "If you want to compute one or several new target(s), run ./cado-nfs.py /tmp/cado.6sp3cynu/p2dd20.parameters_snapshot.0 target=<target>[,<target>,...]"

Then I get:

How should I deal with this problem

I get cado-nfs from Files ?? master ?? cado-nfs / cado-nfs ?? GitLab (inria.fr). version may be 3.0.0.
I installed the ubantu22.0.4 virtual machine on VMware??and use G++ compiler
     Looking forward to hearing from you.
