Question

我想将熊猫df的数据库转换为sqlite3

我正在使用这段代码：

con = sqlite3.connect('\path\db.db')
df = pd.read_sql('select * from db', con)

引用我得到了什么

Traceback (most recent call last):
    df = pd.read_sql('select * from db', con)
  File "PATH\pandas\io\sql.py", line 403, in read_sql
    pandas_sql = pandasSQL_builder(con)
  File "PATH\pandas\io\sql.py", line 578, in pandasSQL_builder
    if _is_sqlalchemy_connectable(con):
  File "PATH\pandas\io\sql.py", line 43, in _is_sqlalchemy_connectable
    import sqlalchemy
  File "PATHPython38-32\lib\site-packages\sqlalchemy\__init__.py", line 12, in <module>
    from sqlalchemy.sql import (
  File "PATHPython38-32\lib\site-packages\sqlalchemy\sql\__init__.py", line 7, in <module>
    from sqlalchemy.sql.expression import (
  File "PATHPython38-32\lib\site-packages\sqlalchemy\sql\expression.py", line 32, in <module>
    from sqlalchemy import util, exc
  File "PATHPython38-32\lib\site-packages\sqlalchemy\util\__init__.py", line 7, in <module>
    from .compat import callable, cmp, reduce, defaultdict, py25_dict, \
  File "PATHPython38-32\lib\site-packages\sqlalchemy\util\compat.py", line 202, in <module>
    time_func = time.clock
AttributeError: module 'time' has no attribute 'clock'

此代码是否有问题？此错误的原因是什么？

Answer 1

SQLALchemy 0.7.10确实很老。大概6.5岁。它使用了time.clock……

：1：DeprecationWarning：time.clock在Python 3.3中已弃用，将从Python 3.8中删除：改用time.perf_counter或time.process_time

SQLite3-熊猫模块'时间'没有属性'时钟'
