[SOLVED] AttributeError: module 'pandas' has no attribute 'Float64Dtype'

I am using Azure ML Notebook to run both python and R code in notebook cells. I have installed python packages pandas 1.1.5 and rpy2 3.5.4 but when I run the following lines of code:

%load_ext rpy2.ipython
print("ankit")

I get the following error message:

 AttributeError: module 'pandas' has no attribute 'Float64Dtype'

Can anyone please help to resolve this error ? Any help would be appreciated.

Complete error is as following:
