will be helpful for those in need You are conflating the Cloud Datalab way with the gbq way. You should use one or the other. To do this from Cloud Datalab, once you have created the data, you can just use:
code :
suri_table.insert_data(df)

wish help you to fix your issue %%gcs returns bytes objects. To read it use BytesIO from io (python 3)
code :
mybucket = storage.Bucket('bucket-name')
data_csv = mybucket.object('data.csv')

%%gcs read --object $data_csv --variable data

df = pd.read_csv(BytesIO(data_csv), sep = ';')

it should still fix some issue Before loading large datasets into Google Cloud Datalab: Make sure to consider alternatives such as those mentioned in the comments of this answer. Use sampled data for the initial analysis, determine the correct model for the problem and then use a pipeline approach, such as Google Cloud Dataflow, to process the large dataset.
There is an interesting discussion regarding Datalab performance improvements when downloading data from BigQuery to Datalab here. Based on these performance tests, a performance improvement was merged into Google Cloud Datalab in Pull Request #339. This improvement does not appear to be mentioned in the release notes for Datalab but I believe that the fixes are included as part of Datalab 1.1.20170406. Please check the version of Google Cloud Datalab to make sure that you're running at least version 1.1.20170406. To check the version first click on the user icon in the top right corner of the navigation bar in Cloud Datalab then click About Datalab.

I wish did fix the issue. After diving deeper in the BigTable mechanics, it seems that the python client executes a gRPC ReadRows call when you call table.read_rows(). That gRPC call returns a streaming response of rows in key order over HTTP/2 (see the docs).
If the API returns data per row it seems to me that the only useful way to consume that response is row based. There seems to be little use in trying to load that data in a columnar format to avoid having to loop over the rows.

may help you . Google Cloud Bigtable supports the Apache HBase 1.0+ APIs, so you can use the Apache Spark HBase connector. There are several examples here:
