TypeError: Cannot interpret 'CategoricalDtype(categories=['no', 'yes'], ordered=False)' as a data type

I just upgraded all my python libraries, and now my previous code is started to fail. I'm using blaze with pandas. Here is my method code

blaze.data(res)

res contains below data

             col1         age  ...                                           col31  year
0            yes    55-64  ...                                             NaN  2011
1             no    25-34  ...                                             NaN  2011
2             no    55-64  ...                                             NaN  2011

I'm using below dependencies

- python=3.6.11=h4d41432_2_cpython
- blaze=0.11.3=py36h4e06776_0
- odo=0.5.1=py36h90ed295_0
- pandas=1.0.5=py36h0573a6f_0
- numpy=1.19.1=py36h3849536_2

I'm getting the following error

  File "cytoolz/functoolz.pyx", line 667, in cytoolz.functoolz.pipe

TypeError: Cannot interpret 'CategoricalDtype(categories=['no', 'yes'], ordered=False)' as a data type

It's failing to parse second column values.
