# Pretrained Models

This directory contains pretrained VAE and reconstruction network models obtained during the WP3 of the EVENFLOW EU project.

These models have been trained on a pre-processed version of the bulk RNA-Seq TCGA datasets of either KIRC or BRCA, independently (see data availability in the respective section).

## Usage

### Loading Models in Python
 
See [renalprog](https://www.github.com/gprolcastelo/renalprog) for the needed VAE and NetworkReconstruction objects.


```python
import torch

import json
from pathlib import Path
import huggingface_hub as hf
from renalprog.modeling.train import VAE, NetworkReconstruction

# Configuration
cancer_type = "KIRC"  # or "BRCA"

    repo_id="gprolcastelo/evenflow_models",
    filename=f"{cancer_type}/config.json"
)

# Load configuration
with open(vae_config_path, "r") as f:
    vae_config = json.load(f)

print(f"VAE Configuration: {vae_config}")

# Download VAE model weights

# Initialize and load VAE

    mid_dim=vae_config["MID_DIM"],
    features=vae_config["LATENT_DIM"]
).to(device)

checkpoint_vae = torch.load(vae_model_path, map_location=device, weights_only=False)
model_vae.load_state_dict(checkpoint_vae)
model_vae.eval()

print(f"VAE model loaded successfully from {cancer_type}")

# ============================================================================
# Load Reconstruction Network
# ============================================================================

# Download network dimensions
network_dims_path = hf.hf_hub_download(

)

# Load network dimensions

recnet_model_path = hf.hf_hub_download(

# Initialize and load Reconstruction Network
model_recnet = NetworkReconstruction(layer_dims=layer_dims).to(device)
checkpoint_recnet = torch.load(recnet_model_path, map_location=device, weights_only=False)

model_recnet.eval()

print(f"Reconstruction Network loaded successfully from {cancer_type}")

# ============================================================================
# Use the models
# ============================================================================

# Example: Apply VAE to your data
# your_data = torch.tensor(your_data_array).float().to(device)
# with torch.no_grad():
#     vae_output = model_vae(your_data)
#     recnet_output = model_recnet(vae_output)
