Valueerror : mmap length is greater than file size

I have got a problem when I was loading the model to initial the model,there exists yolo-tiny.weights in bin content and the yolo-tiny.cfg is in cfg/vi/.and I am sure the road is right.could you solve it for me.

flow --model /home/sys324/pycharm/Zxx_Project/darkflow-master/cfg/v1/yolo-tiny.cfg --load /home/sys324/pycharm/Zxx_Project/darkflow-master/bin/yolo-tiny.weights

I had this error come up as well. Please advise.

This error arises when the weights are either corrupted or does not match the cfg file you chose.

If it is corrupted then just download the weights again and make sure that the weights are downloaded fully.

And for the cfg make sure you are using the weights for the cfg file you chose, typically the naming I most cases are the same. If you are using tiny_yolo weights then use the tiny_yolo.cfg.
