Any idea? Thanks!

I've opened a similar topic on torch-thrift about the same issue. I've just disabled the ipc_static part in CMakeList.txt (line 46) and got everything to work. My question concerns on the usefulness of that ipc_static/thrift_static stuff, i.e., how really needed it is for the code to (properly) run.

Hi,

It's not needed at all to run. It's an artifact of our internal needs for a completely static linked binary. Not sure why it's failing you as it works on a completely new ec2 instance. Do you have the latest torch installed?

Yes, I have the latest torch installed.

Tried it on two separate machines with an updated torch version and got the same thing. Only by removing that static stuff from CMakeList.txt I was able to install the package

It was added to Torch here:

fixes them.
