问题
I'm getting this error in a google colab notebook. Do I need to install something or it's just not possible to use pypy inside colab? I've tried this simple script:
%%pypy
print("hello")
# Couldn't find program: 'pypy'
If I run %lsmagic the output is the following, in which pypy is present.
Available line magics:
%alias %alias_magic %autocall %automagic %autosave %bookmark %cat %cd %clear %colors %config %connect_info %cp %debug %dhist %dirs %doctest_mode %ed %edit %env %gui %hist %history %killbgscripts %ldir %less %lf %lk %ll %load %load_ext %loadpy %logoff %logon %logstart %logstate %logstop %ls %lsmagic %lx %macro %magic %man %matplotlib %mkdir %more %mv %notebook %page %pastebin %pdb %pdef %pdoc %pfile %pinfo %pinfo2 %pip %popd %pprint %precision %profile %prun %psearch %psource %pushd %pwd %pycat %pylab %qtconsole %quickref %recall %rehashx %reload_ext %rep %rerun %reset %reset_selective %rm %rmdir %run %save %sc %set_env %shell %store %sx %system %tb %tensorflow_version %time %timeit %unalias %unload_ext %who %who_ls %whos %xdel %xmode
Available cell magics:
%%! %%HTML %%SVG %%bash %%bigquery %%capture %%debug %%file %%html %%javascript %%js %%latex %%perl %%prun %%pypy %%python %%python2 %%python3 %%ruby %%script %%sh %%shell %%svg %%sx %%system %%time %%timeit %%writefile
Automagic is ON, % prefix IS NOT needed for line magics.
Eventually are there some alternatives? I've already tried numba but due to the fact that mostly need it to preprocess data I usually need obejcts that seems to make numba unable to compile in a nopython mode. So I'm looking for something more flexible like pypy.

You can use pypy in Colab once you install it on the Colab VM:
!apt-get install pypy
%%pypy
import sys
print(sys.executable)
# /usr/bin/pypy
