问题
Lots of the BigQuery examples begin with:
import gcp.bigquery as bq
But I get ImportError: No module named gcp.bigquery
whenever I try to run this.
How do I install this library?
I'm working in a virtualenv with python 2.7. I've tried pip install gcp
, pip install gcloud
, and pip install google-api-python-client
.
None of them help and I can't find any documentation. Help!
UPDATE: the reason I want to use gcp
is that I want to get data from BigQuery, preferably in CSV form, from within a Python script. If there's a better way to do this, I'm all ears...
回答1:
You should try a simple:
$ pip install --upgrade google-api-python-client
as discussed in the documentation.
Furthermore, gcp.bigquery
is part of Google Cloud DataLab, so you should try from that angle if you are still interested.
回答2:
Use pandas and google-api-python-client. The function you are looking for is pd.read_gbq http://pandas.pydata.org/pandas-docs/stable/generated/pandas.io.gbq.read_gbq.html

For anyone with this problem, it looks like the datalabs library was updated and now you should import things differently.
import datalab.bigquery as bq
回答4:
If you're accessing BigQuery in python, you can do that using the gcloud library.
First, install the gcloud
library:
$ pip install --upgrade gcloud
Then, after setting up your auth and project info, you can make api calls in python like this (adapted from the gcloud-python docs):
from gcloud import bigquery
client = bigquery.Client()
datasets, next_page_token = client.list_datasets()
print([dataset.name for dataset in datasets])
(As someone mentioned previously, you can also do it using the google-api-python-client.)

gcp.bigquery is a library specific to Cloud Datalab (as would be any samples you saw such an import in).
回答6:
You can build the library from datalab teams' content on github:
- Clone the repository https://github.com/GoogleCloudPlatform/datalab/
- Run tools/initenv.sh
- Run sources/build.sh
- There you have it under sources/build/
Hope this helps. Executing the docker image locally does not work for me at least.
