Thank you for the contribution. I have tried run the code and somehow the result does not match the result from daisy(). Any suggestion?

Are you testing this in a public dataset which I can reproduce the problem?

  Yes. I just re-run the code on your provided gower_pdist.ipynb without changing anything and the result is slightly off.
  
  UPDATE
  
  This is the matrix I get after running the code several times using both Jupiter and Spider

Hi,

Thanks for these details. I've just ran this with python anaconda 3.5.1 and jupyter 4.1.0 and got same sresults from daisy (there are three values that may have a slight diff from daisy, but my math is good).

Could you please send me the version and flavor of pyhton you are running on your side? This way I will be able to repoduce the problem.

Regards,

  Hi,
  
  I use Anaconda 4.3.0 (64-bit) Python 2.7.13 on Spider 3.1.2 and on Jupiter 4.3.1 on both Windows and Mac and all them produce the same result.

  It works. One more tiny comment: in your Jupyter notebook, you skip step 3 in your heading. I am happy to close this ticket. Once again, thank you for your contribution.
