Python3.6熊猫“无法导入DataFrame”

Question

I have an issue with using Python3.6 and pandas to read csv data. Everything was working fine then I did a system update on my Arch install

sudo pacman -Syu

Then when trying to run any script with pandas imported I got the following error:

  from .sqldf import *
  File "/usr/lib/python3.6/site-packages/pandasql/sqldf.py", line 3, in <module>
  from pandas.io.sql import to_sql, read_sql
  File "/usr/lib/python3.6/site-packages/pandas/io/sql.py", line 23, in <module>
  from pandas.core.api import DataFrame, Series
  ImportError: cannot import name 'DataFrame'

I get this error with any code importing pandas, such as:

import pandas
print ('Hello')

So it it an issue with pandas, but I cannot seem to find the root of the cause online anywhere. Any help with this problem would be greatly appreciated!

Full Error:

  File "/usr/lib/python3.6/site-packages/pandas/__init__.py", line 42, in <module>

  File "/usr/lib/python3.6/site-packages/pandas/io/sql.py", line 23, in <module>
    from pandas.core.api import DataFrame, Series
ImportError: cannot import name 'DataFrame'

This may also be relevant, my most recent pacman log, any idea if any of these changes could have caused the problem?

Note: If I run in a Python terminal it seems there are no issues, just the script.

Shown is the import working in Python terminal but failing when ran in the simple script shown it errors out.

Answer 1

So this was a big waste of time, the error seemed to have nothing to do with the script that I was using to test. Once I moved it out of the directory it was in everything worked fine.
