ImportError: cannot import name 'Argument' from 'utils' when running #32

Closed ashwinwriter closed 2 years ago

ashwinwriter commented 2 years ago

Hi,

Sorry if it's a dumb question, I am new to python scripts. I am getting this errors when running sample scripts from repository.

ontap-rest-python/volume_operations.py at master · NetApp/ontap-rest-python · GitHub

Error: File "//volume_operations.py", line 23, in from utils import Argument, parse_args, setup_logging, setup_connection, get_size ImportError: cannot import name 'Argument' from 'utils' (/usr/local/lib/python3.9/site-packages/utils/init.py) [root@centos9 /]#

Many thanks!

It sounds like, from the /usr/local/lib/python3.9/site-packages/utils path in your error, that you have a package called "utils" installed. But the utils in the example scripts refers to the utils.py file here: https://github.com/NetApp/ontap-rest-python/blob/master/examples/python_client_library/utils.py

So the expectation of the example script is that you are running it from the examples/python_client_library directory so that it can import that local utils.py file.

Hi Rob,

Thank you for replying so quick. I didn't expect that. Much appreciated.

Your observation makes sense. I am absolutely new to this new stuff (scripting to be honest).

So, what I did is, I copied the 'utils.py' content, copied it to the /location of my centos9 and saved it as utils.py, and I ran it.

[root@centos9 /]# python3.9 utils.py It worked, no complain.

Next, I ran the volume_operations script and hurray, it didn't complain. Thanks for your help.

I see different error this time, I will review it but if you have any suggestions please do reply.

[root@centos9 /]# python3.9 volume_operations.py Password:

The problem here is that the script wants you to pass the cluster management IP: https://github.com/NetApp/ontap-rest-python/blob/9632d237ab12b76fd3b032ce47fa6db0a8df2857/examples/python_client_library/volume_operations.py#L425-L426

So you would want to run it like this:

[root@centos9 /]# python3.9 volume_operations.py --cluster 1.2.3.4

Where you replace 1.2.3.4 with whatever your IP actually is.

Thanks, Rob. That was so dumb of me. I have been running scripts with cluster IP as it clearly states in the sample, but I was so excited that I left my common sense in the bin.

It works, I ran it again with cluster IP.

[root@centos9 /]# python3.9 volume_operations.py -c x.x.x.x -u admin -p xxxxxx

I really appreciate your patience and help. I am glad you are there to help. Hopefully, I can pick up basic stuff from here on.
