For TASK 1/2 :

export SANAME=challenge
gcloud iam service-accounts create $SANAME

gcloud projects add-iam-policy-binding $DEVSHELL_PROJECT_ID --member=serviceAccount:$SANAME@$DEVSHELL_PROJECT_ID.iam.gserviceaccount.com --role=roles/bigquery.admin

gcloud projects add-iam-policy-binding $DEVSHELL_PROJECT_ID --member=serviceAccount:$SANAME@$DEVSHELL_PROJECT_ID.iam.gserviceaccount.com --role=roles/storage.admin
gcloud iam service-accounts keys create sa-key.json --iam-account $SANAME@$DEVSHELL_PROJECT_ID.iam.gserviceaccount.com

export GOOGLE_APPLICATION_CREDENTIALS=${PWD}/sa-key.json
gsutil cp gs://$DEVSHELL_PROJECT_ID/analyze-images.py .

Now go to open editor -> analyze-image.py

For task 4 :

python3 analyze-images.py $DEVSHELL_PROJECT_ID $DEVSHELL_PROJECT_ID

For task 5 :

Big Query pr aa jao :

Chap do :

SELECT locale,COUNT(locale) as lcount FROM image_classification_dataset.image_text_detail GROUP BY locale ORDER BY lcount DESC

Bss Congo fir ..

Chlo thanks for supporting :>
