AttributeError: module 'pandas' has no attribute 'tslib' when I use blaze module

Question

I have below environment

Linux "16.04"
Python 3.6.11
conda 4.8(latest)

I've two dependencies in my project

- blaze=0.11.3=py36_0
- pandas=1.0.5=py36h0573a6f_0

While resolving conda and pip dependencies, it is throwing below error

Traceback (most recent call last):
AttributeError: module 'pandas' has no attribute 'tslib'

    @convert.register((pd.Timestamp, pd.Timedelta), (pd.tslib.NaTType, type(None)))

It looks like blaze is failing to get proper pandas version. So I tried to upgrade blaze(so that it'll auto download nested latest version of pandas), but I found that there are no updates for the blaze library. https://github.com/blaze/blaze/tags

Also I see that 0.11.3 version is compatible with conda latest version, https://docs.anaconda.com/anaconda/packages/py3.6_linux-64/

Please let me know what is the best solution to resolve this...

Answer 1

I was having a similar problem with odo which has a blaze dependence, I installed the github package and it was fine. Try installing the GitHub version of blaze and see if it works.

Answer 2

I found the solution on github.

There are problem with pandas.py file inside odo package. So in Ubuntu you need to go to Computer/usr/local/lib/python3.8/dist-packages/odo/backends/ and open pandas.py. Than in line 94, change

pd.tslib.NaTType

to

type(pd.NaT)
