some methods and modules do not work

[navidboy70]

Describe the bug I am trying to use geemap,eemont and ee to derive some indices from sentinel-2 dataset from GEE python API in VSCode. the problem is that some methods and modules can not be recognized by python and I face error. I also copied the exact scripts from your tutorials, but the problem still exists.

To Reproduce import ee, eemont, geemap

   S2 = (ee.ImageCollection("COPERNICUS/S2_SR")
            .filterBounds(ROI)
            .filterDate("2020-01-01","2021-01-01")
            .preprocess()
            .maskClouds()
            .scaleAndOffset()
            )
    S2online = S2.spectralIndices(["NDVI","kNDVI","NDWI","SeLI"],online = True).median()

AttributeError: 'ImageCollection' object has no attribute 'preprocess'

Screenshots If applicable, add screenshots to help explain your problem.

Setup (please complete the following information):

• OS: Windows
• python version 3.10 & 3.8
• eemont version 0.3.5
• earthengine-api version [e.g. 0.1.32]

Additional context Add any other context about the problem here.

Hi @navidboy70!

I tried the code that you sent (with another ROI since I don't have access to the one you're using) and everything works fine in VS Code, JN, and Colab. Please try the following:

1. The preprocess method was created for eemont>=0.2.0. Check you are actually using eemont with a version greater or equal to 0.2.0. You can check the version with eemont.__version__. You can update eemont with pip install -U eemont.
2. The preprocess method is actually a short method for object.maskClouds().scaleAndOffset(): You shouldn't use these methods after calling preprocess.

If the problem persists, please paste here the complete code with a screenshot of the error.

Best,

David

Hi David, I managed to fix the problem. Thank you very much. Unfortunately, I have faced another problem with your library in the google earth engine code editor. I write your spectral code : 'var spectral = require("users/dmlmont/spectral:spectral");', but it causes an error : 'In users/dmlmont/spectral:spectral-constants Line 51: None is not defined'

I did not have problem with it since 2 days ago, but now it does not work. I will be really thankful, if you response it. best regards, Navid

Sorry, it was an error when translating from Python to JavaScript. It has been fixed! :)

Bets regards,

Hello David, I am using your library 'eemont' in python environment (VSCode), when I use '.preprocess()' method in my code it faces an error 'ee.ee_exception.EEException: Request payload size exceeds the limit: 10485760 bytes.' . However, without it, it prints the output. ' S2_1 = ( eemont.ee.ImageCollection(dataset) .filterBounds(state) .filterDate('2021-09-23','2021-10-23') .preprocess())
