SyntaxError: invalid syntax

推荐答案

如果减去 % 符号之一，它应该可以工作.最小的例子:

If you subtract one of the % symbols it should work. Minimal example:

import google.datalab.storage as storage
import pandas as pd
from io import BytesIO

mybucket = storage.Bucket('BUCKET_NAME')
data_csv = mybucket.object('data.csv')

uri = data_csv.uri
%gcs read --object $uri --variable data

df = pd.read_csv(BytesIO(data))
df.head()
