[FIXED] Maximum Recursion Depth Exceeded: Python Azure ServicePrincipalCredentials

Issue

I am calling a new object to manage an Azure Resource and using the Azure python packages. While calling it, i get a maximum depth exceeded error however if I step through the code in a python shell I don't get this issue. Below is the init method

class WindowsDeployer(object):
    def __init__(self, params):
        try:
             print("executes class init")
             self.subscription_id = '{SUBSCRIPTION-ID}'
             self.vmName = params["vmName"]
             self.location = params["location"]
             self.resource_group = "{}-rg".format(self.vmName)
             print("sets variables")

             # Error is in the below snippet, while calling ServicePrincipalCredentials
            self.credentials = ServicePrincipalCredentials(
                client_id='{CLIENT-ID}',
                secret='{SECRET}',
                tenant='{TENANT-ID}'
            )

            # Does not reach here...
            print("creates a credential")
            self.client = ResourceManagementClient(self.credentials, self.subscription_id)

Instead, it exits with the following message: maximum recursion depth exceeded

I have tried to increase the recursion limit to 10000 and that has not solved the issue.

Pip freeze: azure==4.0.0 azure-common==1.1.4 azure-mgmt==4.0.0

The last line keeps going until it hits the recursion limit

Solution

Thanks for the help above. The issue was with my gevent packages (not sure exactly what) however adding upgrading gevent and adding the following lines fixed it.

import gevent.monkey
gevent.monkey.patch_all()
