Neither mask_rcnn.yml nor requirements.txt work on Ubuntu 18.04.4

[Mateus-M-Reis]

when I try to create an environment with the mask_rcnn.yml file, it returns me the following output:

So I cloned my environment that I think has the necessary packages for computer vision tasks.

conda create -n mask_rcnn --clone vision

When I try to install the requirements.txt file I receive the following output:

pip install -r requirments.txt
