kalix 0.2.4.dev1

Python interface for Kalix: hydrological modelling and Pixie (Gorilla-compressed) timeseries I/O

kalix (Python)

Python interface for Kalix.

Current functionality:

• read and write Pixie files (.pxt, .pxb)

Planned:

• model loading & simulation
• programmatic model manipulation and building
• optimisation

Install

pip install kalix

Usage

import kalix

# Read a .pxt/.pxb pair into a DataFrame
df = kalix.read_pixie("results.pxb")
print(df.head())

# Write a DataFrame back out
kalix.write_pixie("out.pxb", df)

The DataFrame index is a UTC DatetimeIndex; each column is one timeseries.

read_pixie accepts either extension (or no extension) and finds both files:

kalix.read_pixie("results.pxb")  # same as
kalix.read_pixie("results.pxt")  # same as
kalix.read_pixie("results")
