Import error

[theodore-weld]

When first importing johansen (in python3), it gives me a "module not found error".
Prior, it also gave me errors relating to python 2 vs 3 in the johansen.py file, but I edited those to conform to python 3.

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-1-a1c691410a6a> in <module>()
----> 1 import johansen

~/.local/lib/python3.6/site-packages/johansen/__init__.py in <module>()
----> 1 from .johansen import Johansen

~/.local/lib/python3.6/site-packages/johansen/johansen.py in <module>()
      2 from statsmodels.tsa.tsatools import lagmat
      3 
----> 4 import critical_values
      5 
      6 

ModuleNotFoundError: No module named 'critical_values'

However, in ~/.local/lib/python3.6/site-packages/johansen, the critical_values.py file is there!
This question / problem may be better suited for StackOverflow--however I thought I would try here.

Any insight is appreciated.
Edit: added sys.path.append('/home/theo/.local/lib/python3.6/site-packages/johansen') andimport johansen worked properly, however from johansen import coint_johansen did not work properly.

edit johansen.py and replace line at top where he had "import critical_values" to "from johansen import critical_values"

I got it to work after doing that,

That worked.
