My python-flask web application which uses "import seaborn" is working fine in my local machine. But when I am trying to deploy the web application on server (IIS from microsoft), the application crashes. Since its not possible to console log error in server, so I enclosed my "import seaborn" statement in try-except clause and logged the traceback error in a file.

This is what I am getting:enter image description here

Any idea why this is happening. Deployment of the application to the server is stopped because of this error.

  • It's a bit shocking - to run flask app on IIS. Are you obliged to use Windows and IIS to run your flask app? – Nurjan Jun 13 '17 at 06:01
  • Yup no other choice. Organizational constraints. :( any idea? – majumderS Jun 13 '17 at 06:45
  • There were similar questions on SO. This is one of them https://stackoverflow.com/questions/6823316/python-on-iis-how. Just make sure you install all packages including `seaborn`. I also recommend using virtualenv if you don't use it. – Nurjan Jun 13 '17 at 08:18
  • See we have already deployed a number of python flask applications on iis and they are working fine. As for seaborn insatallation, all packages are installed properly. Any idea what that error:"underlying buffer has been detached" mean? – majumderS Jun 13 '17 at 09:15
  • Also, "import seaborn" is working fine in cmd of the iis server but when we are trying to deploy it we are getting this error. – majumderS Jun 13 '17 at 09:21
  • @Nurjan Was there any resolution to this? I'm having a weird interaction with seaborn and IIS. Same error and I can't figure out what it means. – Daniel Scott Nov 18 '20 at 20:30

Looks like wfastcgi and ipython don't like eachother.

Uninstalling ipython solved the problem for me (although I can't use my jupyter notebooks anymore).
