Problem with export of ImageCollection

[tabea-schultestrathaus]

Hi there,

I have some issues with downloading an ImageCollection and I would appreciate any help! I'm following an earlier tutorial from this community.

Here's my code:

import ee
import random
from geetools import batch

ee.Authenticate(auth_mode='localhost')
ee.Initialize(project='ee-user')

seed = random.randint(0, 10000)

collection = (ee.ImageCollection('COPERNICUS/S2_SR_HARMONIZED')
              .filterDate('2023-01-01', '2023-01-31')
              .filter(ee.Filter.stringContains('MGRS_TILE', '20M'))
              .filter(ee.Filter.lt('CLOUDY_PIXEL_PERCENTAGE', 10))
              .randomColumn('randomKey', seed)
              .sort('randomKey')
              .limit(3)
              .select(['B2', 'B3', 'B4', 'B8']))

print('Number of images', collection.size().getInfo())

size = collection.size().getInfo()
clist = collection.toList(size)
for i in range(size):
    image = ee.Image(clist.get(i))
    iid = image.id().getInfo()
    name = 'jan_'+iid
    print('downloading '+ name)
    batch.image.toLocal(image, name)

And here's the error:

This script is not compatible with version 1.0 of the lib as exportation has not been refactored yet. Could you try using 0.6.14 ? Alternatively can you look at my answer in https://github.com/gee-community/geetools/issues/256 ?

[tabea-schultestrathaus]

Hi, thanks for your reply! I already downgraded to 0.6.14. Is it really a problem with batch?

[12rambau]

I think yes, maybe the latest changes to the tools module have conflict in the batch context, or the collection you have is a featureCollection nwhich sounds strange.

The problem is that there was no tests before so I'm building them on the spot every time I refactor an existing method. There are many cases where I need multiple iteration to cover all the edge cases. The v1 of the lib will eventually be more stable but i still need to work on batch
