Unknown parameter 'TagSpecifications' for ec2 run_instances() method

With Boto3 Version 1.4.5 on Python 3.6, using the keyword TagSpecifications on the run_instances() method of boto3.client(‘ec2’) results in an ‘Unknown parameter on input’ error.

Example:

       ec2 = boto3.client('ec2')
        tags = [
                     {'Key':'project','Value': 'foo'},
                     {'Key': 'owner', 'Value': 'walter'},
               ]
        tag_specification = [{'ResourceType': 'instance', 'Tags': tags},]

        response = ec2.run_instances(ImageId=image_id,
                                     MaxCount=requested_number,
                                     MinCount=1,
                                     TagSpecifications=tag_specification,
                                     InstanceType=instance_type,
                                     DryRun=dry_run)

yields:

    main('one_site')

botocore.exceptions.ParamValidationError: Parameter validation failed:
Unknown parameter in input: "TagSpecifications", must be one of: DryRun, ImageId, MinCount, MaxCount, KeyName, SecurityGroups, SecurityGroupIds, UserData, InstanceType, Placement, KernelId, RamdiskId, BlockDeviceMappings, Monitoring, SubnetId, DisableApiTermination, InstanceInitiatedShutdownBehavior, PrivateIpAddress, Ipv6Addresses, Ipv6AddressCount, ClientToken, AdditionalInfo, NetworkInterfaces, IamInstanceProfile, EbsOptimized

Sure enough, TagSpecifications isn’t listed in the “must be one of:” list.

Ah, sorry. Upgrading botocore from 1.5.8 to 1.5.95 seems to have solved the problem. Might I suggest bumping the minimum botocore version in the boto3 wheel file to 1.5.95 (or whatever is most appropriate)?

Great! Thanks.
