bbdesign not working in python 3.8.5

[kakila]

bbdesing is not working on Python 3.8.5

This is the error if I try to run the example in the docstring

----> 1 doe.bbdesign(3)

~/virtual_enviroments/hamopt/lib/python3.8/site-packages/pyDOE/doe_box_behnken.py in bbdesign(n, center)

---> 66     H_fact = ff2n(2)
     67     # Now we populate the real DOE with this DOE
     68

Same Issue. You can test here: https://colab.research.google.com/drive/1paIe2xzREicgILvJSsE7PLlcRXbLNMJu#scrollTo=5rI7gtaEeDdp

[francoisbres]

with python 3, you have to install pydoe2 instead of pydoe

from pyDOE2 import fullfact, ff2n, fracfact, fold, pbdesign, bbdesign, ccdesign, lhs
bbdesign(3)

Hello @francoisbres thx for your help.

Yes. It's works using :

!pip install pyDOE2

from pyDOE2 import fullfact, ff2n, fracfact, fold, pbdesign, bbdesign, ccdesign, lhs
bbdesign(3)
