importError

Hi nzahasan,

I installed pyheclib successfully but when I import it, I got the following error message:
++++++++++++++++++++++++++
import pyheclib as phl
Traceback (most recent call last):
File "", line 1, in
ImportError: /data/miniconda3/envs/nos-s100/lib/python3.7/site-packages/pyheclib.cpython-37m-x86_64-linux-gnu.so: undefined symbol: inflateEnd
++++++++++++++++++++++++++
Do you have any suggestions about how to fix it? Thank you!

@ywang910516 need a little more information for example your os.

[ywang910516]

Thanks for your quick reply. I am using Python 3.7.3 on an AWS Linux instance.

@ywang910516 seems like a zlib issue, I have only tested this on ubuntu. can you install for the python your distribution provided & check.

[ywang910516]

I just installed zlib by this command: "sudo apt-get install zlib1g-dev"
but when got the same error when I import pyheclib...

@ywang910516 can you try without anaconda.

[ywang910516]

It seems all my python (python3.7 and python3.9) are installed under miniconda3. I have some environments and python scripts running operationally... I don't want to mess up them. Could you please explain a little bit about how to try without anaconda? I am usually confused about the relationship between anaconda, miniconda, and python itself...

From my side this issue is not reproducible, can you try on another small vm with ubuntu 20.04. It should come with python3.8.
