Some incompatible packages?

[jiapei100]

I'm using Python 3.6.5 under Ubuntu 18.04

kaggle-cli 0.12.13 has requirement cliff<2.9,>=2.8.0, but you'll have cliff 2.12.0 which is incompatible.
kaggle-cli 0.12.13 has requirement lxml<4.1,>=4.0.0, but you'll have lxml 4.2.1 which is incompatible.
kaggle-cli 0.12.13 has requirement MechanicalSoup<0.9,>=0.7.0, but you'll have mechanicalsoup 0.10.0 which is incompatible.
kaggle-cli 0.12.13 has requirement progressbar2<3.35,>=3.34.3, but you'll have progressbar2 3.38.0 which is incompatible.

Cheers
