问题
Hi I was able to install packages in google colab with pip, using:
!pip install....
but i am not able to install any package from conda-forge. I tried:
!conda install -c conda-forge cartopy
thanks in advance!

One way to get it is to just Unzip the conda
package to a directory directly.
Get you required
conda
package fromanaconda.org
, download it.Decompress them and copy them into the library path
Here's an example to install faiss
from anaconda using this way.

Another option (that I've not tried) is to connect to a custom runtime (kernel in Jupyter parlance). https://research.google.com/colaboratory/local-runtimes.html
The workflow would be:
- create a conda environment with the things you want + jupyter_http_over_ws
- start a notebook on your machine and connect colab as described
This may not be what you are looking for though as it does require local installations (and is therefore no longer zero-install).

I use the decompress method with cartopy. Here's the result.
# get package then extract
!wget https://anaconda.org/conda-forge/cartopy/0.16.0/download/linux-64/cartopy-0.16.0-py36h81b52dc_2.tar.bz2
!tar xvjf cartopy-0.16.0-py36h81b52dc_2.tar.bz2
!cp -r lib/python3.6/site-packages/* /usr/local/lib/python3.6/dist-packages/
# install dependencies
!pip install shapely pyshp
!apt install libproj-dev libgeos-dev
# finally
import cartopy

In general, this is a way to install a package in conda from Colab:
!wget https://repo.continuum.io/miniconda/Miniconda3-4.5.4-Linux-x86_64.sh
!bash Miniconda3-4.5.4-Linux-x86_64.sh -bfp /usr/local
# Append path to be able to run packages installed with conda
import sys
sys.path.append('/usr/local/lib/python3.6/site-packages')
# Install packages from Anaconda
!conda install -y [package]
This works for packages like -c pslmodels taxcalc
(notebook).
However, cartopy
is a complicated package that's creating problems here, I think because the above requires an older version of conda
*, which is no longer compatible with cartopy
. Here's a Colab notebook that uses this version and fails because cartopy
requires the shapefile
package, and this is one that uses the latest version of conda and isn't recognized upon import
.
* For example, here are versions of the taxcalc
notebook that install the latest installer and run conda update conda before installing taxcalc
; import taxcalc
isn't recognized in either case. See this GitHub issue.
