qgis-earthengine-plugin cannot be use

[dongjief]

Hi, I just met the problem, and the qgis-earthengine-plugin cannot be use.
When the plugin had been installed, the problem appeared.
My OS and QGIS version are Windows 10, QGIS 3.10 'A Coruña'.

I thought that it may be caused by different directory definition (/ or ), but when I change to the Mac, the same problem still appear.

The detailed information is showed as bellow.

Couldn't load plugin 'ee_plugin' due to an error when calling its classFactory() method

Could be some firewall issue, can you try:

1. install ee python api separately from qgis by running conda install earthengine-api and then run earthengine authenticate and follow instructions, if that works then restart QGIS
2. open tinyurl.com in a browser, this is used to shorten the auth url during plugin setup.

[GokulGeo]

Earth engine plugin works in 3.8 will it work in 3.10?

[gena]

@GokulGeo - it should, it was tested with 3.8 and 3.10.

[GokulGeo]

It is working fine in 3.10. I am totally a beginner in python, I hope there will be sample exercises in the future to explore in qgis.

Hi everyone, I have a similar problem, I thought it was a problem of SSL Certificates but they are already update and I cannot operate the plugin, the message is as follows:

[giswqs]

@GokulGeo Here are examples.

[gena]

The first fix for this authentication type of error is to try authenticating using the command-line version of EE. Please follow https://developers.google.com/earth-engine/command_line and install EE Python API using Conda and then authenticate it via earthengine authenticate.

@giswqs nice to see examples for the plugin, but this is a bit off-topic here. I'd post this on the developers' forum.

[geomenke]

I am having similar issues getting the plugin to authenticate on my Windows 10 box. I have installed earthengine-api via OsGeo4W shell and Anaconda and successfully authenticated EE at the command prompt. However, when I paste the authentication code into the plugin window I always get the message below. I've tried it on ubuntu with similar results.. I have tried this on QGIS v3.12-1 and 3.10-4. Any guidance appreciated.

Installing earthengine-api under QGIS python in parallel to QGIS EE plugin is a road to troubles, since calling import ee will be ambiguous - don't do that (uninstall it). Instead, install earthengine-api under some separate python/anaconda installation. There is no need to copy/paste code in this case, just authenticate using a separate python installation + earthengine-api, follow instructions, once earthengin-api is authenticated - a new file will be written in ~.config\earthengine\credentials. The EE plugin will pick up that file during QGIS start and will use to talk to EE.

[geomenke]

@gena Thanks for the feedback and help. Now I have a single installation of earthengine (anaconda) and see the ~.config\earthengine\credentials file. However, QGIS does not pick up on it. When QGIS launches the Authorization window opens instructing me to follow the instructions in the opened web page and paste the resulitng auth token here.

[gena]

That's weird,

what QGIS version are you using? - just saw it specified above

One option I'd think of is to uninstall the plugin and make sure there is nothing from the earthengine-api left in the QGIS directory.

This could be a new EE API issue as well.

... also the dialog text needs to be fixed 🙂

[gena]

So, try to:

• Uninstall QGIS plugin
• Start QGIS and type in Python console: import ee - this should fail

[geomenke]

I unistalled the plugin.
import ee failed at the python console
Checked my plugin folder and there is nothing related to ee there
Reinstalled the plugin and at that point can import ee at the console.
However, when I close QGIS and restart I get the Authorization message

[gena]

Hmm, I've just removed my auth file and tried to authenticate from QGIS on my machine as well ... everything worked. I've sent you an email, let's find out why this fails on your machine. This could be some firewall issue, but then authenticating using CLI would also fail.

[dongjief]

Hi, Gena,

I can use the qgis-earthengine-plugin now.
The method I used was set a proxy command in Python Console of QGIS. It is shown as below.

import ee
import os
os.environ['HTTP_PROXY'] = 'http://127.0.0.1:1081'
os.environ['HTTPS_PROXY'] = 'http://127.0.0.1:1081'
ee.Initialize()

Then the plugin can be applied.

[gena]

It seems that 404 sometimes means that account is not fully whitelisted, I'll extend FAQ to include this case.
