Question

我使用sqliteBrowser来检查我正在使用的日期集中的表是否存在，但是在尝试查询表时，我仍然收到此错误。有什么想法吗？

import pandas as pd
    import graphlab.aggregate as agg
    import graphlab as gl
    import numpy as np
    import sqlite3
    from scipy.sparse import csr_matrix
    import matplotlib.pyplot as plt
    %matplotlib inline

    pd.set_option('display.float_format', lambda x: '%.3f' % x)



MusicData = sqlite3.connect("msd.sqlite3")

plays_df = gl.SFrame.from_sql(MusicData, "SELECT * FROM song")

错误：

OperationalError：没有此类表格：使用graphlab sframe的歌曲
