How to build libraries via conda on colab.research?

Question

So I want to use python-occ library. It requires conda-forge to be build. I try to install it in basic notebook

!wget -c https://repo.continuum.io/archive/Anaconda3-5.1.0-Linux-x86_64.sh
!chmod +x Anaconda3-5.1.0-Linux-x86_64.sh
!bash ./Anaconda3-5.1.0-Linux-x86_64.sh -b -f -p=conda3
!export PYTHONPATH=./conda3/lib/python
!export PATH=./conda3/bin/:$PATH
!conda install -y -c conda-forge -c dlr-sc -c pythonocc -c oce pythonocc-core

Yet it will install a package into condas python. How to make oit install package into global python or use its python\libs folder for cels interpritation?

So what one must do to build/install stuff with conda in colab?

Answer 1

The following seems to work:

!wget -c https://repo.continuum.io/archive/Anaconda3-5.1.0-Linux-x86_64.sh
!chmod +x Anaconda3-5.1.0-Linux-x86_64.sh
!bash ./Anaconda3-5.1.0-Linux-x86_64.sh -b -f -p /usr/local
!conda install -y --prefix /usr/local -c <<<your wish>>>>

import sys
sys.path.append('/usr/local/lib/python3.6/site-packages/')

Answer 2

I once needed a library that was available only through Conda too. My solution is that

• !pip install all the requirements of that library
• unzip(decompress) the conda file i.e. pythonocc-core-0.18.1-py36hdfe9f0f_110.tar.bz2 into the right directory.

And it worked for me.
