Hi, I tried installing fenics on Colab using the following code: !apt-get install -y -qq software-properties-common python-software-properties module-init-tools !add-apt-repository -y ppa:fenics-packages/fenics !apt-get update -qq !apt install -y --no-install-recommends fenics Unfortunately, the …

Actually, restarting the runtime (Runtime->Restart Runtime) after installing fenics seems to be all you need. [sjplural] ModuleNotFoundError after successful pip install in Google Colaboratory python, pip, google-colaboratory asked by sjplural on 11:00P…

@dparsons , thanks for fixing that. I just tried to installing fenics on colab a few minutes back, it did successfully install. However, it is unable to import dolfin. import dolfin as df print ('dolfin version:', df.__version__) --------------------------------------------------------------------…

Can you locate where it is installed? What is the output of !dpkg -L fenics? Most likely not in /usr/local/lib/python3.6/dist-packages… If it’s not then simply add that path to sys, using import sys;sys.path.append(<your path>)

This what I get when I try !dpkg -L fenics /. /usr /usr/share /usr/share/doc /usr/share/doc/fenics /usr/share/doc/fenics/changelog.gz /usr/share/doc/fenics/copyright

@Hari , did you delete your local installation from pip install? What does dpkg -l *dolfin* return?

@dparsons , this is what I get Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==============-============-…

Please run dpkg -l *dolfin* | cat to get the full information. Can you confirm you have deleted the local installation files from pip install ?

@dparsons , yes, I did (factory)reset the runtime on Colab, so that should have removed any previous installations including pip install. Here’s the output for dpkg -l *dolfin* | cat Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-…

What is the output from python3 -c "import dolfin; print(dolfin.__version__); print(dolfin.__path__)" and dpkg -l *petsc* | cat ?

Sorry, I (Hari) am replying to you in with a different account because I have reached the new user reply limit. python3 -c "import dolfin; print(dolfin.__version__); print(dolfin.__path__)" 2019.2.0.dev0 ['/usr/lib/petsc/lib/python3/dist-packages/dolfin'] [4303537e1512:03986] *** Process received …

@dparsons , I have pasted a link to the colab notebook. [image] Google Colaboratory
