'Python3.5 ImportError: libpython3.5m.so.1.0: cannot open shared object file: No such file or directory

I am using Ubuntu 14.04 LTS, 64-bit. I downloaded Python3.5.1 Gzipped tarball source from https://www.python.org/downloads/release/python-351/.

Then installed using

./configure
sudo make install

Then I upgrade pip by

sudo pip install --upgrade pip

it upgraded pip to 8.1.2, which is the latest version. Then installed matplotlib package using

sudo pip install --upgrade matplotlib

Now, when I import matplotlib into python, I get

Python 3.5.1 (default, Jun  9 2016, 14:37:08)

ImportError: libpython3.5m.so.1.0: cannot open shared object file: No such file or directory

Please advise on how to fix this?

Thank you.

Most people installed matlibplot through Anaconda or Canopy instead of installing it as an individual module. Usually if you have an error from _path, it means something wrong with your installation or compilation. _path is related to compiled c extentions. You can read the installation page of matlibplot. But the easiest way to fix it is to install Anaconda and you won't worry about a lot of things. Good luck!

I ran into a similar issue. It's because my libpython binaries were installed to /usr/local/lib/ and the program was looking for libpython under /usr/lib/. Making a symbolic link in /usr/lib/ solved the problem:

sudo ln -s /usr/local/lib/libpython3.8.so.1.0 /usr/lib/libpython3.8.so.1.0

or, in your case,

sudo ln -s /usr/local/lib/libpython3.5m.so.1.0 /usr/lib/libpython3.5m.so.1.0
