create partition err: create gamma table has err:[4294967294]

i readed the blog on zhihu a few days ago

i'm using vearch 3.1.0 and the latest version of python plugin

it seems my installation is ok, and i continue to run the db & space create command 

db test created but then I got error"{"code":550,"msg":"create partition err: create gamma table has err:[4294967294] "}"

i am new to vearch and AI, what's nest should i do.
