Usage

Loading the Model

Below are two safe ways to load the trained policy depending on what you have available.

Option A — Load the full Stable-Baselines3 model (.zip)

python

from stable_baselines3 import PPO
from stable_baselines3.common.vec_env import VecNormalize
import os

# Create or reconstruct an environment similar to the one used for training
# e.g. `env = make_your_env(...)` — replace with your env factory
env = ...

# If you saved VecNormalize separately, load and wrap your env first
if os.path.exists("models/vecnormalize.pkl"):
	vec = VecNormalize.load("models/vecnormalize.pkl", env)
	vec.training = False
	vec.norm_reward = False
	env = vec

# Load the full model (policy + optimizer state)
model = PPO.load("models/ppo_xauusd.zip", env=env)

Option B — Load weights saved as SafeTensors into a fresh PPO policy

python

from safetensors.torch import load_file
import torch
from stable_baselines3 import PPO
from stable_baselines3.common.vec_env import VecNormalize
import os

# Create or reconstruct the same environment used for training
env = ...

# If you have VecNormalize statistics, load them and wrap the env
if os.path.exists("models/vecnormalize.pkl"):
	vec = VecNormalize.load("models/vecnormalize.pkl", env)
	vec.training = False
	vec.norm_reward = False
	env = vec

# Instantiate a PPO model with the same policy architecture
model = PPO("MlpPolicy", env)

# Load SafeTensors state dict and convert values to torch.Tensor if needed
raw_state = load_file("models/ppo_xauusd.safetensors")
state_dict = {k: (torch.tensor(v) if not isinstance(v, torch.Tensor) else v) for k, v in raw_state.items()}

# Load weights into the policy
model.policy.load_state_dict(state_dict)

# Ensure the model has the same env wrapper
model.set_env(env)

Notes:

Option A is preferred when ppo_xauusd.zip is available (it contains the entire SB3 model).
Option B is useful when only the policy weights were exported as SafeTensors. Ensure the policy architecture and observation/action spaces match the original training setup.
Always set vec.training = False and vec.norm_reward = False when running inference.

For Full Inference

To use the model for trading, you'll need to:

Set up the trading environment (XAUUSDTradingEnv)
Load VecNormalize stats
Run predictions

Note: This is a simulation model. Use with caution in real trading.
