pandas == condition fails

environment

  • magic 07.2
  • mojo 25.2.0 (26172dfe)
  • pandas 2.2.3

pandas.mojo

from python import Python

def main():
    pd = Python.import_module("pandas")
    data = Python.dict()
    data['col1'] = [1,2,3]
    df = pd.DataFrame(data)
    res = df[df['col1'] >= 2]
    print(res)

This works correctly.
But if the condition is

res = df[df['col1'] == 2]

this throws exception :

Unhandled exception caught during execution: False
mojo: error: execution exited with a non-zero result: 1

or

Unhandled exception caught during execution: <cyfunction item_from_zerodim at 0x7f50ea1cdf20> returned a result with an exception set
mojo: error: execution exited with a non-zero result: 1

Is it a known problem?
Is it a syntax problem?
