ContextualVersionConflict: Datalab + Cloud Vision

Question

I'm getting a ContextualVersionConflict when making a call to Google Cloud Vision API

I have installed/upgraded the libraries I can think of, to no avail. The code works on my local machine, the issue just happens in Datalab.

Code:

!pip install --upgrade google-cloud-bigquery
!pip install --upgrade google-api-python-client
!pip install --upgrade google-api-core
!pip install --upgrade google-cloud-vision

#below from https://cloud.google.com/vision/docs/detecting-safe-search
def detect_safe_search_uri(uri):
    """Detects unsafe features in the file located in Google Cloud Storage or
    on the Web."""
    from google.cloud import vision
    client = vision.ImageAnnotatorClient()
    image = vision.types.Image()
    image.source.image_uri = uri

    response = client.safe_search_detection(image=image)
    safe = response.safe_search_annotation

    # Names of likelihood from google.cloud.vision.enums
    likelihood_name = ('UNKNOWN', 'VERY_UNLIKELY', 'UNLIKELY', 'POSSIBLE',
                       'LIKELY', 'VERY_LIKELY')
    print('Safe search:')

    print('adult: {}'.format(likelihood_name[safe.adult]))
    print('medical: {}'.format(likelihood_name[safe.medical]))
    print('spoofed: {}'.format(likelihood_name[safe.spoof]))
    print('violence: {}'.format(likelihood_name[safe.violence]))
    print('racy: {}'.format(likelihood_name[safe.racy]))

#Sample URI    
detect_safe_search_uri("https://www.victoriassecret.com/p/404x539/tif/1a/d2/1ad2f0b4a7054d81ad178b941f3a8b80/395481036_OM_F.jpg")

You would have to specify a different version than default one for your google-cloud-vision library (for some reason it doesn't work with the latest one)

!pip install google-cloud-vision==0.29.0

import google.datalab.storage as storage
import google.datalab.utils as utils
from io import BytesIO

from google.cloud import vision
from google.cloud.vision import types
from PIL import Image, ImageDraw
