ImportError: The serialization library could not be found

[adamryczkowski]

I have an error with the current (just cloned) Serialbox and Python 3.5. I have a serialized fields in the tmp-adam-dwarf0b/build folder with filenames: dwarfs.json, dwarfs_u3.dat and dwarfs_x.dat. Now I want to inspect the fields with the following Python code:

adam@adam-g551jm:/home … pos/serialbox/python$ ipython3
Python 3.5.2 (default, Nov 17 2016, 17:05:23) 
Type "copyright", "credits" or "license" for more information.

IPython 2.4.1 -- An enhanced Interactive Python.

In [1]: from serialbox import Serializer

In [3]: ser = Serializer(datapath,'dwarfs')

Why it throws the error? What can I do?

It cannot find the serialbox c-library. You will have to set PYTHONPATH to your python subfolder in your serialbox installation directory.

Example:

export PYTHONPATH=your_serialbox_install_path/python
ipython
....

We are also discussing this in the README.

Problem solved.
