I can write up the specs, but they’re much more complicated now. Serialized files are actually tars containing 4 other files - one listing tensors, one listing storages, one with storage data and one with system info (long size, endianness, etc.). I think for this use case it would by much simpler to take advantage of some more standardized format, with a C library supporting loading from it (such as HDF5 or protobuf). Do you think that would be ok?
