Description
Pandas version checks
-
I have checked that this issue has not already been reported.
-
I have confirmed this bug exists on the latest version of pandas.
-
I have confirmed this bug exists on the main branch of pandas.
Reproducible Example
import numpy.core.numeric as numeric
import pandas as pd
df = pd.DataFrame() # Without this there is no crash
dtype = numeric.dtype(float)
print(dtype) # Just for run outputIssue Description
Executing this code works as expected. But when I place a PyCharm debugger breakpoint on any line after dtype = numeric.dtype(float) and run in PyCharm debug mode I get the following exception:
Traceback (most recent call last):
File "/home/leonid/.local/share/JetBrains/Toolbox/apps/PyCharm-P/ch-0/221.5787.24/plugins/python/helpers/pydev/pydevd.py", line 1491, in _exec

File "/home/user/code/some_dir/some_dir/test.py", line 7, in <module>
dtype = numeric.dtype(float)
TypeError: 'NoneType' object is not callable
This behavior has been observed in numpy ( numpy/numpy#21008 ) and determined to be related to a Cython issue. The issue has been resolved by the latest Cython release (0.29.30) and the newest numpy release (1.22.4) that was built using that Cython version seems to be doing fine.
Would it be possible to expedite a minor pandas version update, completely similar to 1.4.2 but built using the new Cython? This has been a major pain point for ML development at my company for quite some time, so I wanted to check in and see if perhaps anything can be done.
Expected Behavior
I can use the debugger on the above code.
