Reproduction instructions

An error occures when I use the read_index function to load the saved index, the program just can't go through!

[bitsun]

please be more specific on how we can reproduce this bug.
e.g. Which index type were you reading. It is better if you can provide the source code.
Note that this is a tailored window port for my own project usage. It does not support all the index types. So far only Linear Index, IFV,IVF_Flat,IVF_PQ index are supported in this windows port

[zengjiechuan]

The code was running in win7 Visual Studio 2015.
The write_index function work. I tried to read several types of index include IndexFlat, IndexIVFFlat, IndexIVFPQ and failed. It seemed the problem occured in the line 776 of index_io.cpp when execeute "READVECTOR (idxf->xb)", I 'm not sure.

What data did you use there for your index io test. Is it random generated float vectors or some project specific data? And what do you mean by saying it did not go through? the program just hung there and ran forever, or it just crashed ?

[zengjiechuan]

The data is just some normal number that I saved in .txt files. I said "the program just can't go through" means that it just hung there >_<!!
BTW, tell you a good news bitsun. I succeed in transplanting the newest faiss to windows(just cpu version) by following your code, and I can use the read_index function now. Could you please tell me your email？Maybe we can communicate later. Thx
