Error when plt.savefig

[LuciusMos]

I got an FileNotFoundError when executing plt.savefig(gen_train_plt_name(args), dpi=600) in train.py/train()

  File "/home/LAB/penghao/.conda/envs/torch-sparse/lib/python3.6/site-packages/matplotlib/pyplot.py", line 842, in savefig
    res = fig.savefig(*args, **kwargs)

Same error.
I've fixed it by adding a directory "results" at the root directory in the project.
Good Luck!
