Hi  am using gurobi on google colab and I set the license with this piece of code. But it is not working now. The error is below. My license is for container (as mentioned in the error) and I use google colab but I do not know why it is not working.

GurobiError: Web license service only available for container environments

e = gp.Env(empty=True)

wlsaccessID = os.getenv('GRB_WLSACCESSID','my api')

e.setParam('WLSACCESSID', wlsaccessID)

licenseID = os.getenv('GRB_LICENSEID', 'my id')

e.setParam('LICENSEID', int(licenseID))

wlsSecrets = os.getenv('GRB_WLSSECRET','my code')

e.setParam('WLSSECRET', wlsSecrets)

e.setParam('CSCLIENTLOG', int(3))

e.start()

  Hi Alireza,

  Please note that due to a recent update to Google Colab, the WLS licensing process described below may not currently work. We are working on a fix for this. In the meantime, you can still use Colab by following the instructions in the "Using a Local Runtime" section below.

  Please refer to this Knowledge Base article: Google Colab: Installation and Licensing – Gurobi Support Portal

  Best regards,
  Matthias

  Hi there, 

  I am still getting this issue. Is there an ETA on this issue being resolved? Back when it worked I loved solving my models in colab and letting them run in the background. 

  Best,

  David

  This should get fixed with our new Gurobi 10.0 release, which is scheduled for first half of November 2022.
