Installation

There are two different methods for hydroDL installation:

Create a new environment, then activate it

conda create -n mhpihydrodl python=3.7
conda activate mhpihydrodl

1) Using PyPI (stable package)

Install our hydroDL stable package from pip (Python version>=3.0)

pip install hydroDL

2) Source latest version

Install our latest hydroDL package from github

pip install git+https://github.com/mhpi/hydroDL

Note: If you want to run our examples directly, please download the example folder (It contains the code and data for these examples).

There exists a small compatibility issue with our code when using the latest pyTorch version. Feel free to contact us if you find any issues or code bugs that you cannot resolve.

Quick Start:

The detailed code for quick start can be found in tutorial_quick_start.py

See below for a brief explanation of the major components you need to run a hydroDL model:

# imports
from hydroDL.model.crit import RmseLoss
from hydroDL.model.rnn import CudnnLstmModel as LSTM
from hydroDL.model.train import trainModel
from hydroDL.model.test import testModel

# load your training and testing data 
# x: forcing data (pixels, time, features)
# c: attribute data (pixels, features)
# y: observed values (pixels, time, 1)
x_train, c_train, y_train, x_val, c_val, y_val = load_data(...)

# define your model and loss function
model = LSTM(nx=num_variables, ny=1)
loss_fn = RmseLoss()

# train your model
model = trainModel(model,
    x_train,
    y_train,
    c_train,
    loss_fn,
)

# validate your model
pred = testModel(model,
             x_val,
             c_val,
)

Examples

Several examples related to the above papers are presented here. Click the title link to see each example.

The dataset used is NCAR CAMELS dataset. Download CAMELS following this link. Please download both forcing, observation data CAMELS time series meteorology, observed flow, meta data (.zip) and basin attributes CAMELS Attributes (.zip). Put two unzipped folders under the same directory, like your/path/to/Camels/basin_timeseries_v1p2_metForcing_obsFlow, and your/path/to/Camels/camels_attributes_v2.0. Set the directory path your/path/to/Camels as the variable rootDatabase inside the code later.

Computational benchmark: training of CAMELS data (w/ or w/o data integration) with 671 basins, 10 years, 300 epochs, in ~1 hour with GPU.
