## Description of request:

## Environment:

NCI gadi login node

conda/analysis3

## What executed:

```auto
$ module load conda/analysis3
$ python
>>> from netCDF4 import Dataset

```

## Actual results:

Traceback (most recent call last):  
File “”, line 1, in   
File “/g/data/xp65/public/apps/med\_conda/envs/analysis3-26.02/lib/python3.11/site-packages/netCDF4/ **init**.py”, line 3, in   
from .\_netCDF4 import \*  
ImportError: /g/data/xp65/public/apps/med\_conda/envs/analysis3-26.02/lib/python3.11/site-packages/netCDF4/../../../././libmpi\_mpifh.so.40: undefined symbol: ompi\_instance\_count

## Expected results:

No error

## Additional info:

Earlier today I was running the same jobs with conda/analysis3-26.01 as the default, so I assume the default version has just changed to conda/analysis3-26.02

Hi Susan,

We’re having a few issues that we’re currently grinding away at solving.

As of right now, the `26.02` environment is broken. I think `26.03` is working, but I’d need to double check.

I would recommend using `conda/analysis3-26.01` explicitly for now. Fingers crossed `26.02` & `26.03` will be working as intended very soon (later today or tomorrow).

Sorry for the disruption.

Hey Susan,

`conda/analysis3-26.02`, (and all other conda environments, including `26.01` and `26.03`) should now be working again.
