RecursionError when opening a dataframe with Pandas 1.1.0 in the kernel and 1.0.5 in Spyder

Description

What steps will reproduce the problem?

import pandas as pd
df = pd.DataFrame({"a":range(10),"b":range(10)})

Try to open df by double clicking on the DataFrame in the variable explorer.

This was previously working fine. I believe that a recent install of spyder-kernels to my virtual environment caused this problem, but I’m not sure how.

To avoid having to install spyder in every virtual environment I works with, I just install spyder-kernels in the venv, launch spyder from my base environment, and point the python interpreter to the python instance inside my venv. This process has been working fine, until I just had to a create a new venv for a project. I repeated this process and am now getting this error. This only happens when the python interpreter is pointing to my venv interpreter, not base spyder.

Quick googling seems like this may be related to incompatible versions of ipykernel and spyder-kernels (?) https://github.com/python-poetry/poetry/issues/2133

-version of spyder-kernels = 1.9.3 -version of ipykernel: 5.3.4, which was installed with spyder-kernels

@ccordoba12 if I have my spyder environment with pandas 1.1.1 and connect it to a kernel with pandas 1.0.5 it works as expected and the error doesn’t exist. I think we need to bump our version of pandas for avoiding this error and we can report this problem to pandas so they can be aware of this behavior.

@ccordoba12 I was able to reproduce this error by creating a new environment with the latest version of pandas and connecting this one as python interpreter. My base environment has pandas 1.0.5 and the new environment has pandas 1.1.1
