问题
On Ubuntu 18.04 with python 3.7.3, I'm attempting to import pandas but this fails because it can't find _lzma.
I've verified that _lzma is installed with dpkg:
/usr/lib/python3.7/lib-dynload/_lzma.cpython-37m-x86_64-linux-gnu.so. Oddly, _lzma is not a dependency of pandas (as specified by pip3).

I was running into this exact same issue today! I was able to fix it though.
Pandas just put out a new version 0.25.0 on July 18th and changing the version back to 0.24.2 fixed this issue for me.
I hope this works for you too!

I have the same issue using pyenv. You don't need to rollback pandas.
To fix import errors, I've removed python:
$ pyenv uninstall 3.7.1
Installed dependencies:
$ sudo apt-get install liblzma-dev
and reinstalled version:
$ pyenv install 3.7.1
