'BatchServiceClientConfiguration' object has no attribute 'signed_session' #288

Open aizest opened 4 years ago

Get "'BatchServiceClientConfiguration' object has no attribute 'signed_session'" exception when creating pool with the following Python code.

new_pool = batch.models.PoolAddParameter( id='GPU-Pool', virtual_machine_configuration=batch.models.VirtualMachineConfiguration( image_reference=image_ref_to_use, container_configuration=container_conf, node_agent_sku_id='batch.node.ubuntu 16.04'), vm_size='Standard_NC6', target_low_priority_nodes=1) batch_client.pool.add(new_pool)

I'm using the following related python packages under Python 3.7:

azure-batch==8.0.0 azure-common==1.1.23 azure-nspkg==3.0.2 azure-storage==0.36.0 msrestazure==0.6.2

Please advise, thanks!
