All results empty

[HVEC-lab]

Version 0.3.0 in some cases returns empty results. As yet I have not figured out what triggers this. Will return to version 0.2.6 for now and will let you know if I find out more.

Hello, I also got empty results on Windows but OK on MacOS. Have you figured out yet? @HVEC-lab

As yet I have not figured out what triggers this.

Can you provide a reproducible example that we can use to debug this?

[datpthus]

@ocefpaf my students install 0.3.0 and this is what they got.

@datpthus it is virtually impossible for me to reproduce that from a cropped screenshot. Can you send code, in text, with a minimal example that reproduces the problem?

[datpthus]

@ocefpaf sorry I misunderstood. Here is the code.

import numpy as np
import matplotlib.pyplot as plt
import pandas as pd
from scipy import signal
import utide
from datetime import datetime as dt
import matplotlib.dates as mdates
import scipy.interpolate as sc

KLM = pd.read_excel('data.xlsx', dtype={'Y':str,'M':str,'D':str, 'H': str})
dt=KLM['Y']+'/'+KLM['M']+'/'+KLM['D']+' '+KLM['H']+ ':00:00'
KLM ['datetime']=pd.to_datetime(dt)
KLM=KLM.set_index('datetime')

time=mdates.date2num(KLM_jul.index.to_pydatetime())

coef = utide.solve(time,KLM_jul['sealevel'].values,
lat = 20.68,
method='ols',
conf_int='MC')

and then it says "solve: matrix prep ... solution ... done." but nothing is produced
Thanks a lot. And I attached here the data file
data.xlsx

This works: https://nbviewer.org/urls/gist.githubusercontent.com/ocefpaf/db8d637d24ea63a9be3878eb7167911f/raw/d9acf296b010be7fa0f05eec89b561c1b6070bd6/demo.ipynb

You are passing the wrong input as dates. Latest version takes the pandas datetime index directly now.

Ah thanks! So no need to calculate time with respect to epoch anymore?
