Setting BiqQuery environment variable Error

I was following Google's BigQuery get started page on how to set the credentials, but something is still incorrect. These are the steps I followed:

1. Set up a free Service Account and created my key. Saved it to a folder.

2. Set the environment variable in Anaconda Prompt as set GOOGLE_APPLICATION_CREDENTIALS=C:\Users\$Name\OneDrive\Templates\api\BigQuery\creds.json.

3. In Python:

   from google.cloud import bigquery

   client = bigquery.Client()

This resulted in the following error. How do I fix it?

Traceback (most recent call last):
