Error AttributeError: module 'ESMF' has no attribute 'api'

I installed the required library but got the following error when import xesmf. It has problem when import ESMF. I am working under CentOS 6.5. I installed xESMF using conda install -c conda-forge esmpy.

Below is the error:

AttributeError Traceback (most recent call last)

Seems the same as #19. Does the workaround there work?

[yugaophd]

I did try but it seems irrelevant. the error happened before importing netcdf:

error---> 11 import ESMF.api.constants as constants 12 from ESMF.util.decorators import deprecated, netcdf 13 from ESMF.interface.loadESMF import _ESMF

I think this is related to the Operating System(Centos) because ESMF works fine under Mac OS.

I can only find CentOS 6.6 on Docker Hub: https://hub.docker.com/_/centos/

It seems to work fine:

$ docker pull centos:6.6
$ docker run --rm -it centos:6.6 /bin/bash
$ yum install -y wget bzip2 tar which
$ cd $HOME
$ wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh -O miniconda.sh
$ bash miniconda.sh -b -p $HOME/miniconda
$ export PATH=$HOME/miniconda/bin:$PATH
$ conda install -c conda-forge esmpy
$ python -c 'import ESMF'  # no error

OK I found a terribly old AMI on AWS: https://aws.amazon.com/marketplace/pp/B00IOYDTV6 (It is so old that it doesn't even support recent hardware types!)

But I can still run the above commands to install and import ESMPy without problems. Not sure how to reproduce your error...
