Odd that my email didn't come through to you. Anyway, since 'which'
finds it, the paths seem correct. Alex' suggestion to install the
development library is a good one however. I have had problems in the
past with mixed Anaconda python installations and Ubuntu distro ones.
I (like you) had the conda in a subdir of my home directory though, so
I found it was easiest for me to just disable the conda paths e.g. by
commenting out
#export PATH="/home/gedare/anaconda3/bin:$PATH"
in my .bashrc was sufficient for me

Then, I could install/use the Ubuntu distributions Python2/3 packages
without conflicts.
