Download granule not working

[bidhya]

I am trying to run a simple Quickstart as instructed on this first page:
import icepyx as ipx query = ipx.Query( # Collection short name "ATL06", # Bounding box [-55, 68, -48, 71], # Time bounds ['2019-02-20','2019-02-28'], ) query.download_granules('/tmp/icepyx')

However, I get the following Attribute error:
`AttributeError Traceback (most recent call last)
Cell In[1], line 10
1 import icepyx as ipx
2 query = ipx.Query(
3 # Collection short name
4 "ATL06",
(...) 8 ['2019-02-20','2019-02-28'],
9 )
---> 10 query.download_granules('/tmp/icepyx')

File [~/Github/icepyx/icepyx/core/query.py, in Query.download_granules(self, path, overwrite)
1022 if hasattr(self, "last_order") is None:
1023 raise ValueError("No order has been placed yet.")
-> 1024 status = self.last_order.status()
1025 if status["status"] == "running" or status["status"] == "accepted":
1026 print(
1027 (
1028 "Your harmony job status is still "
1029 f"{status['status']}. Please continue waiting... this may take a few moments."
1030 )
1031 )

AttributeError: 'Query' object has no attribute 'last_order'
I followed the installation instruction like this:mamba env create --name icepyx-env --channel conda-forge icepyx
mamba activate icepyx-env
mamba update icepyx
`
Current version installed is 2.0.0

I know there is message about harmony job status, but I do not know how to fix this?

If icepyx is not working for a while, do you have alternative suggestions to download icesat-2 data?

Hello @bidhya! Great to see you here again, and thanks for the excellent issue post.

There was a bug in v2.0.0 that only recently got fixed (#715), and I've been sick so I only today got it into a released version. v2.0.1 is now available from PyPI (you could try pip install icepyx in your virtual environment, and then restart your kernel if you're using JupyterNotebook), but it usually takes a day or two for conda-forge (and thus mamba) to pick up the new release (which is where the installation instructions get the library from). Alternatively, if you re-create your environment after this page shows v2.0.1 as the latest version, you should be all set (but please let us know if not!)

Thanks, @JessicaS11 , yes, happy to catch-up. I think we can close this issue because some of my colleagues reported success.

However, I have mix feelings! When I install the latest version (2.0.1) using mamba, I get esoteric massages likely emitted by Harmony-api about authentication.

When I install it directly by from git, those errors are gone. Installing directly from pip also seems to be working.

I can reopen this or different issue once I work more with this, and have more information to share.

Going back to quickstart example on this github page, I had to add the following line:
order = query.order_granules()
I think this triggers harmony job. Now only the following download code works:
query.download_granules('/tmp/icepyx')

Otherwise, we get the following attribute error: AttributeError: 'Query' object has no attribute 'last_order'

If your testing shows similar issue, we should add order = query.order_granules() to quickstart.

Yes - please open a new issue if you are able to pinpoint where the authentication errors are coming from. I would also suggest checking the contents of your .netrc file. I've had mine get corrupted before (weird characters, extra spaces, etc.) and that caused issues with earthaccess therefore submitting invalid credentials.

This is documented in #699. Hopefully someone can tackle this issue soon; your suggestion to re-add that line to the quickstart is a good idea if not.

This should be resolved in the latest version on the development branch (not yet released). Please open another issue if you keep running into authentication problems.
