Captioning challenge submission on codalab raising error

[MRishiK99]

I tried evaluating my model on caption test2014 set using the codalab server. I tried submitting the result file as mentioned in the coco tasks page : https://cocodataset.org/#upload.
But I get this error:
WARNING: Your kernel does not support swap limit capabilities or the cgroup is not mounted. Memory limited without swap.
/opt/conda/lib/python2.7/site-packages/matplotlib/font_manager.py:273: UserWarning: Matplotlib is building the font cache using fc-list. This may take a moment.
warnings.warn('Matplotlib is building the font cache using fc-list. This may take a moment.')

I meet similar problem. Have ever solved it?
