gpu support

Modify python-env to allow GPU usage for maskrcnn and dextr.
If no gpu, also works with CPU.
To run with GPU see: https://github.com/NVIDIA/nvidia-docker

@42Max42 please revert to npm instead of yarn

[jsbroks]

Also, why have you created a db folder?

[42Max42]

@jsbroks I changed to yarn because I wasn't able to build
Step 4/19 : RUN npm install -g --quiet @vue/cli@3.3.0 @vue/cli-service@3.3.0 ---> Running in c028bd0fbca2 npm ERR! Unexpected end of JSON input while parsing near '....3","chalk":"^2.4.1",'
I created the db folder for convenience in case of transfer between my machines.

I think its best to figure out why npm is failing before we merge this in

[42Max42]

Hi, npm was failing because of the repositories, (but not yarn). If you want to only use npm it is a bit tricky (but possible).

[jsbroks]

What repository was failing? I dont mind switch if we have a reason too. I use yarn in all my other projects anyway.

[42Max42]

I reverted to the original npm, i changed of network (the original one has an uncertain behavior).

@jsbroks the vue packages were failing on my network. But I prefer yarn.
