This code is in active development and is used within our organization. We are currently not supporting this code for external use and are simply releasing the code to the community AS IS. The community is welcome to submit issues, but you should not expect an active response.
For the code corresponding to our Nature Methods paper, please use the release_1 branch here.
We recommend installation on Linux and an NVIDIA graphics card with 12+ GB of RAM (e.g., NVIDIA Titan X Pascal) with the latest drivers installed.
- We recommend an environment manager such as Conda.
- Install Python 3.6+ if necessary.
- All commands listed below assume the bash shell.
- Clone and install the repo:
git clone https://github.com/AllenCellModeling/pytorch_fnet.git
cd pytorch_fnet
pip install .- If you would like to instead install for development:
pip install -e .[dev]- If you want to run the demos in the examples directory:
pip install .[examples]This will download some images from our Integrated Cell Quilt repository and start training a model
cd examples
python download_and_train.pyWhen training is complete, you can predict on the held-out data with
python predict.pyOnce the package is installed, users can train and use models through the fnet command-line tool. To see what commands are available, use the -h flag.
fnet -hThe -h flag is also available for all fnet commands. For example,
fnet train -hModel training is done through the the fnet train command, which requires a json indicating various training parameters. e.g., what dataset to use, where to save the model, how the hyperparameters should be set, etc. To create a template json:
fnet train --json /path/to/train_options.jsonUsers are expected to modify this json to suit their needs. At a minimum, users should verify the following json fields and change them if necessary:
"dataset_train": The name of the training dataset."path_save_dir": The directory where the model will be saved. We recommend that the model be saved in the same directory as the training options json.
Once any modifications are complete, initiate training by repeating the above command:
fnet train --json /path/to/train_options.jsonSince this time the json already exists, training should commence.
User can perform predictions using a trained model with the fnet predict command. A path to a saved model and a data source must be specified. For example:
fnet predict --json path/to/predict_options.jsonAs above, users are expected to modify this json to suit their needs. At a minimum, populate the following fields and/or copy and paste corresponding dataset values from /path/to/train_options.json
e.g.:
"dataset_kwargs": {
"col_index": "Index",
"col_signal": "signal",
"col_target": "target",
"path_csv": "path/to/my/train.csv",
...
"path_model_dir": [
"models/model_0"
],
"path_save_dir": "path/to/predictions/dir",This will use the model save models/dna to perform predictions on the some.dataset dataset. To see additional command options, use fnet predict -h.
Once any modifications are complete, initiate training by repeating the above command:
fnet predict --json path/to/predict_options.jsonIf you find this code useful in your research, please consider citing our manuscript in Nature Methods:
