Import error

[anoukvlug]

It looks likes the pyclits package is precisely what I am looking for. However after an installation that appeared to be successful, I unfortunately I got the following error message once I tried to import the package:

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)

      6 
----> 7 from data_loaders import *
      8 from empirical_model import EmpiricalModel
      9 from functions import *

ModuleNotFoundError: No module named 'data_loaders'

@jajcayn, could you help me solving this problem?

Dear @anoukvlug
unfortunately, pyclits is pretty old and unmaintained. The reason for your error is that pyclist was developed for python2.7 which is now deprecated. Last time I tried, it did not work with python3.

As for the future of pyclits, unfortunately I do not have the time right now to update it, but I started rewriting core functionality to python3 in branches rewrite/*. If you feel adventurous you might fork the package, checkout rewrite branch and try to finish basic core, then the installation on python3 should work.

Thanks for understanding,
Best,

Nikola

Dear Nikola,
Thank you for your fast and kind reply! Unfortunately it is not the right time for me to be adventures and dive into the code.
Kind regards,
Anouk

Dear Anouk, sidenote to the discussion. The new code that is in my branch = hynek_ refactoring_.... supports Python3. The Python environment is better contained using poetry that support simple packaging and publication of the library.

@mafycek thanks a lot for the advice! I just installed your branch and at first sight it seems to work :)

[mafycek]

Ok, cool! I did not know that it should work in my branch :) Btw. do you use virtual environment and poetry? ---------- Původní e-mail ---------- Od: Anouk Vlug <[email protected]> Komu: jajcayn/pyclits <[email protected]> Datum: 5. 6. 2020 14:38:46 Předmět: Re: [jajcayn/pyclits] Import error (#2) " @mafycek(https://github.com/mafycek) thanks a lot for the advice!

Sorry, I wrote my previous message to early. I thought you meant the branch would work with python 3. So after I installed both the branch and was able able to load the package, I thought it would work. However I kept running into errors, when trying to using the functions. It won't recognize all the functions (some it does recognize though) that are actually there:

e.g.:

AttributeError                            Traceback (most recent call last)
<ipython-input-19-f363db24ae29> in <module>
----> 1 nino34 = clt.data_loaders.load_enso_index("/aop1/avlug/nino34raw.txt", "3.4", start_date = date(1870, 1, 1), 
      2     end_date = date(2017, 7, 1), anom = False)
      3 

AttributeError: module 'pyclits' has no attribute 'data_loaders'

For this I used a python environment (env not venv). I'm not familiar with poetry.

[anoukvlug]

Actually, I wouldn't really need the data_loaders function, however I thought it would be good to get the example to work. As having an example would make it easier to figure out how to solve the error that I am having with the wavelet analysis function:

---------------------------------------------------------------------------

      1 wave, period, scale, coi = wavelet_analysis.continous_wavelet(df['001'].values, dt = dt, wavelet = mother, 
----> 2                                                               dj = dj, s0 = s0, j1 = j1, k=k0)

~/Programs/miniconda3/envs/oggm_env/lib/python3.6/site-packages/pyclits/wavelet_analysis.py in continous_wavelet(X, dt, pad, wavelet, **kwargs)
    137     k = np.arange(1, np.fix(n/2) + 1)
    138     k *= (2. * np.pi) / (n * dt)
--> 139     k_minus = -k[int(np.fix(n-1))/2 - 1::-1]
    140     k = np.concatenate((np.array([0.]), k, k_minus))
    141 

TypeError: slice indices must be integers or None or have an __index__ method

I have no clue if this error would be easy to solve or if it would get tricky and I can better look for another approach to do the wavelet analysis. @mafycek do you maybe know a quick fix for this problem? Or is this going to take quite some time to solve?

[mafycek]

I think that the problem is in the missing __init__ file. I never used the code but I could help you if you send me the command that teriggers the error. I need whole stack to investigate the issue.

Ok, here I see the problem. x/y return s float while x//y returns int. This is deviation beteen Python 3 and 2. ---------- Původní e-mail ---------- Od: Anouk Vlug <[email protected]> Komu: jajcayn/pyclits <[email protected]> Datum: 8. 6. 2020 12:59:06 Předmět: Re: [jajcayn/pyclits] Import error (#2) " Actually, I wouldn't really need the data_loaders function, however I thought it would be good to get the example to work.

The problem should be fixed in the next commit.
