I had imported ITensors and ITensorMPS.  
I tried using ITensors.ITensorMPS: AbstractSum, which had no error.

It looks like the release needs to be updated; in the meantime it looks like the repository is precompiling which you can access by

```auto
pkg> add ITensorParallel#head

```

(or `dev ITensorParallel` if you prefer)
