Hi johnsmith, perhaps there's a problem with the path (typo?) or with the permissions. One thing you could try is to load an arbitrary sgf file from the same folder where you store the network (just using load from the options menu). If GridMaster didn't have read permissions yet it will ask for it and after that I think leelaz should also be able to read from the same folder. Another thing you could try is specify the full path, e.g. "--weights /storage/emulated/0/Download/Networks/network"
