Couldn't get output model.txt after trainning

[yantim]

Thanks for your code! I complied it with cmake and run the TrainDemo.out. It took me 36 minutes to train the data. But after the training, I couldn't find ./data/model.txt, which was supposed to appear in my current directory. How should I fix this problem? Thank you!

It has been a long time since you posted the problem which makes this answer that 'ofstream' cannot automatically create directories along its output path that means you need to create a directory named data at the same directory as TrainDemo.out not be in time, but for the convenience of others encountering this issue I post this.
