AttributeError: type object 'object' has no attribute 'dtype'

Hi,

I am using pandas in one of my Python program. But its throwing following error:

  File "/usr/local/lib/python3.7/site-packages/pandas/core/dtypes/cast.py", line 1221, in construct_1d_arraylike_from_scalar
    dtype = dtype.dtype
AttributeError: type object 'object' has no attribute 'dtype'

How to resolve this?

Thanks

Hi,

This error comes when you are creating empty pandas dataframe. To resolve this you have to upgrade pandas version.

Upgrade pandas to:

pandas==0.25.3 into pandas==1.2.3

or latest version

Command to upgrade pandas:

pip install pandas==1.4.1

Thanks
