**Sorry, Please ignore this topic. This topic is useless and confusing.** 🐖

I am using python [cis.read\_data()](https://cis.readthedocs.io/en/stable/cis_api.html) function to read hdf5 file and its config file. I am getting errors shown in image below:

it works fine with python 2.7

Rename the file to .h5 or something. This is a problem with the Python package `cis`. It is not a Julia problem. Please ask the `cis` folks.

Please look at this [link](https://github.com/PrincetonUniversity/athena/wiki/The-Input-File). My python code below works fine on python2.7.

```julia
from pyfiles import * 
runname='./' #define start dir and file, uncomment below
sane = 1#0 for MAD98, 1 for SANE00
if sane == 1:
    inputfile=runname+'sane00.athinput'
datafile='sane00.prim.01800.athdf'
data=read_data(datafile,athinput=inputfile)

```

I don’t know how to explain my problem to `cis` community.

If you would like to use HDF5.jl, I might be able to help. However, the error you are seeing comes from the cis Python package.

I’m not sure why you would be using Python 2.7, but that is far outside of support.

I suggest downloading miniforge, creating an environment with cis, and then trying to load this with Python 3. If you have problems there, contact the CIS authors:

> **[GitHub - cedadev/cis: Home of the Community Intercomparison Suite.](https://github.com/cedadev/cis)**
>
> Home of the Community Intercomparison Suite. . Contribute to cedadev/cis development by creating an account on GitHub.

Once you have working Python 3 code, please show us what that is.

See this issue in [CIS issues](https://github.com/cedadev/cis/issues/42). Python2.7 reads that file while `CondaPkg` python3.11 don’t read it so there may be something wrong with file address. This `.athinput` is a .txt file.

This is not a good place to address Python issues.

See [https://discuss.python.org/](https://discuss.python.org/)

Provide them with the Python code you posted above.

Yes, there is line in python 2.7 code that is

```julia
from pyfiles import read_athinput 

```

This really has nothing to do with Julia anymore. I suggest you get helf in the Python forum @mkitti mentioned until you have a Python envirnoment+script that can load the data. Then you can essentially copy paste script into Julia with PythonCall.jl and get the data into here. With this last part we can help you. But this is the wrong place for your Python problems. Sorry.

I think this reads like you specified python package versions that do conflict each other in some way, so it’s a Python issue (python environment issue).

Does the code _you need now_ run in Python \>=3.8 alone? Because your versioning and use of PythonCall is requiring that. PyCall is the package that handles Python 2.7. Only try to mix with Julia after you make the code and environment work in pure Python of a compatible version.

> [@raman\_kumar](#):

All you did was copy and paste your question from here and linked this thread. You also shouldn’t expect Python users to be familiar with CondaPkg, post a fresh question there or to the cis developers about any issues with the pure Python work.

> [@mkitti](#):

IIRC CondaPkg was created for PythonCall, does CondaPkg alone share the \>=3.8 limit?

> Does the code _you need now_ run in Python \>=3.8 alone?

I need to run it within Julia script so whatever version it may be, i don’t mind. It would be better if it work in Python\>=3.8. My python code given in 4th post works fine in python2.7 and not in 3.12. In Python i am able to install `pyfiles` easily but got error while installing with CondaPkg in Julia.

```julia
    ~  pip install pyfiles  ✔ 
Requirement already satisfied: pyfiles in ./.pyenv/versions/3.12.2/lib/python3.12/site-packages (0.3.1)

```

🫤Is there any plan to have CIS library api in julia in future?

There we have the reason and the solution. `CondaPkg` does not work with Python 2.x  
So the code you posted in your 4th post has to be changed to run on Python 3. Then you can use it again from Julia.

For the plan of a CIS library API – I am not aware and could not find any approaches. So you either have to start that yourself and/or find people to do that together with.

[pip and conda](https://www.anaconda.com/blog/understanding-conda-and-pip) manage packages differently and thus cannot install from the same repositories. [Mixing conda and pip](https://www.anaconda.com/blog/using-pip-in-a-conda-environment) is so brittle there are guidelines to limit it. You should really be learning this stuff on a Python forum, but this is rudimentary enough to mention quickly.

That matches the pyfiles package I found on PyPI, which I said did not appear to have the function you mentioned. Did you attempt to run the line `from pyfiles import read_athinput` and the rest of the code with this package in Python 3?

@cjdoris said this in [github](https://github.com/JuliaPy/CondaPkg.jl/issues/132#issuecomment-2183860592) 👇  
Make sure you read the full error message! Here is the relevant bit:

```julia
The following package could not be installed
└─ pyfiles * does not exist (perhaps a typo or a missing channel).

```

You’re trying to install a package that isn’t in conda-forge.

😇_What else should i use to install [pyfiles](https://github.com/tianjos/pyfiles) so that it works for my case? What is solution to this issue?_

Did you try to install all the packages you need and run all the related Python code you have in a pure Python (aka no Julia at all) environment of any version, as repeatedly suggested in this thread? What are the outcomes? There was already more than one indication you are dealing with limitations of the Python packages themselves, and you’re the only person here who has the code base to verify it. Doing this work properly is vital to determine where you can look for a solution, if it even exists.
