GEE python：“ee.batch.Export.image.toAsset” "Request had insufficient authentication scopes."

I am getting an error when using python GEE api to save processed image in Colab. The code and the error are as follow:

# Load a landsat image and select three bands.
landsat = ee.Image('LANDSAT/LC08/C01/T1_TOA/LC08_123032_20140515')\
            .select(['B4', 'B3', 'B2'])

# Create a geometry representing an export region.
geometry = ee.Geometry.Rectangle([116.2621, 39.8412, 116.4849, 40.01236])
center = geometry.centroid().getInfo()['coordinates']
center.reverse()

Mapdisplay(center,{'landsat':landsat.getMapId()},zoom_start=7)
# Get band 4 from the Landsat image, copy it.
band4 = landsat.select('B4').rename('b4_mean')\
               .addBands(landsat.select('B4').rename('b4_sample'))\
               .addBands(landsat.select('B4').rename('b4_max'))\

# Export the image to an Earth Engine asset.
task = ee.batch.Export.image.toAsset(**{
  'image': band4,
  'description': 'imageToAssetExample',
  'assetId': 'users/csaybar/exampleExport',
  'scale': 100,
  'region': geometry.getInfo()['coordinates']
})

task.start()

This error occurs due to "task.start()"

I tried to look for a GEE service in the google cloud console to enable it, but couldn't find one. And I want to konw how to fix this problem.

The most recent version of the google earth engine API seems to have introduced some issues with gcloud. Try rolling back to an earlier version using conda install -c conda-forge earthengine-api=0.1.320 and then rerunning your process.

For future reference, most GEE-related questions get asked and answered over at gis.stackexchange.com.
