Pandas cannot import numpy in free-threaded version of 3.13.0b2 #120653
Description
Bug report
Bug description:
- Install python 3.13.0b2 on windows 10, make sure to install free-threaded binaries
- Go to the python installation directory and install pandas by running:
python -m pip install pandas
This will also install numpy - Create file KDTest.py someplace outside of python installation directory with the following content:
from pandas import Timestamp
if __name__ == '__main__':
t1: Timestamp = Timestamp("2023-11-29")
print("Done")
- Assuming python is installed to C:\apps\python313 run
C:\apps\python313\python.exe <path to file>/KDTest.py
Result: all good, Done is printed - Now run:
C:\apps\python313\python3.13t.exe <path to file>/KDTest.py
Result:
Traceback (most recent call last):
File "<path to file>\KDTest.py", line 1, in <module>
from pandas import Timestamp
File "C:\apps\python313\Lib\site-packages\pandas\__init__.py", line 19, in <module>
