I'm using BigQuery for the first time.
client.list_rows(table, max_results = 5).to_dataframe();
Whenever I use to_dataframe() it raises this error:
ValueError: Please install the 'db-dtypes' package to use this function.
I found this similar problem (almost exactly the same), but I can't understand how to implement their proposed solution.

I was able to replicate your use case as shown below.
Easiest solution is to pip install db-dtypes as mentioned by @MattDMo.
Or you can specify previous version of google-cloud-bigquery by creating a requirements.txt with below contents:
google-cloud-bigquery==2.34.3
And then pip install by using command as shown below:
pip install -r /path/to/requirements.txt
Output of my sample replication:
The most robust way to resolve this is to specify that you also want to install the pandas extra dependencies when installing the google-cloud-bigquery package. You'd do this by
- running
pip install 'google-cloud-bigquery[pandas]', or - putting e.g.
google-cloud-bigquery[pandas]==2.34.3in yourrequirements.txt.
