AttributeError: module 'pandas.core.ops'

[mboldin]

I am running on Windows 10 Intel i5 and get import error with

import pandas as pd import text_extensions_for_pandas as tp when run in Jupyter Notebook

the relevant error code is AttributeError: module 'pandas.core.ops' has no attribute '_get_op_name'

imports worked 6 weeks ago fail now and I have no problem with import text_extensions_for_pandas not in Jupyter I tried to create a virtenv just for this problem and installed full pip install of pandas, text_extensions_for_pandas and jupyter and I see the same error only in Jupyter see ERROR in context for more detail

Versions pandas 1.3.5

and Selected Jupyter core packages... IPython : 7.34.0 ipykernel : 6.15.2 ipywidgets : 8.0.2 jupyter_client : 7.3.5 jupyter_core : 4.11.1 jupyter_server : not installed jupyterlab : not installed nbclient : 0.6.7 nbconvert : 7.0.0 nbformat : 5.4.0 notebook : 6.4.12 qtconsole : 5.3.2 traitlets : 5.3.0

I am not 100% sure of the text_extensions_for_pandas versions maybe 0.2.0

UPDATE:

Looking at the Jupyter consoile output, I see:

[IPKernelApp] ERROR | No such comm target registered: jupyter.widget.control [IPKernelApp] WARNING | No such comm: 86364858-6645-43b9-8ee3-3f3405095abe

when import text_extensions_for_pandas fails

A Google search of this error string shows it has been reported for other packages (not text_extensions_for_pandas) as a result of problems related to ipywidgets see https://github.com/jupyter-widgets/ipywidgets/issues/2257

So I doubt it is a fixable TEXT_EXTENSIONS_FOR_PANDAS I will close this issue in a few days if this diagnosis is right, and in meantime hope someone report here a workaround.

FIXED -- for me My jupyter run was pointing to an old pre-alpha version of text_extensions_for_pandas I deleted this, and forced a new install of he module and all is OK The bad line ---> 94 op_name = ops._get_op_name(op, True) was from an old version of tensor.py the latest 0.2.0 version has different code logic for def _create_method(cls, op, coerce_to_dtype=True, result_dtype=None):

Glad this issue is resolved for you now. Let us know if you have any other problems.
