undefined: msgpack.Decode during installation

[georgepar]

Hello,

I encounter the following error when trying to install tarp

webdataset/tarp/tarp/sort.go:44:17: undefined: msgpack.Encode
webdataset/tarp/tarp/sort.go:83:6: undefined: msgpack.Decode                                                                                                                                          

I tried both go get -v github.com/webdataset/tarp/tarp and go get -v github.com/tmbdev/tarp/tarp

Tried with Go version 1.13.8, 1.16.3 and 1.17.

This is a bit weird because I tried to install it a week ago in the same machine (ubuntu 20.04) and it installed without an issue.

I can't reproduce this.

In any case, I have updated tarp to use mpio always, so the dependencies should be correct now no matter what.

Please give it another try.
