@xta0 I’m afraid I spoke too soon.  I thought my build was ok because it was just failing on one of my own bugs, but once I fixed that I’ve run into a couple of issues that I’m not sure how to solve.
I’m getting this error.

libtorch.a(SparseCPUType.cpp.o)’ does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture armv7k

there is no setting for WatchOS to disable bitcode in the build like there is for iOS. is there a way to build the pytorch libs with bitcode enabled?
another issue I was seeing was…

building for watchOS-arm64_32 but attempting to link with file built for watchOS-armv7k

I am attempting to load onto a series 4 watch… any ideas?
Thanks again for your help!!
