[BUG] Function `make_tensordict_primer` Overlooks Batch-Locked Envs #2323

ErcBunny · 2024-07-25T16:05:05Z

Describe the bug

Appending the TensorDictPrimer transform created from LSTMModule.make_tensordict_primer triggers dimension error.

To Reproduce

import torchrl
from torchrl.envs import TransformedEnv, InitTracker, Compose
from torchrl.collectors import SyncDataCollector

env = TransformedEnv(
    original_env,  # a batch-locked environment
    Compose(
        InitTracker(),
        lstm.make_tensordict_primer(),
    ),
)

data_collector = SyncDataCollector(
    env,
    policy,
    frames_per_batch=10,
    total_frames=100,
)

IndexError: Dimension out of range (expected to be in range of [-2, 1], but got -3)

Expected behavior

Should run without error, or when appending the TensorDictPrimer transform, its shapes should be checked.

System info

torchrl==0.4

Additional context

There is a similar issue on: #1493

Reason and Possible fixes

Function make_tensordict_primer overlooks batch-locked envs as it's source code is:

def make_tensordict_primer(self):
    # ...
    return TensorDictPrimer(
        {
            in_key1: UnboundedContinuousTensorSpec(
                shape=(self.lstm.num_layers, self.lstm.hidden_size)
            ),
            in_key2: UnboundedContinuousTensorSpec(
                shape=(self.lstm.num_layers, self.lstm.hidden_size)
            ),
        }
    )

In this case users can manually add the transform with proper shapes.

Checklist

Not exactly sure what is going on in your code but this works fine with me

from torchrl.collectors import SyncDataCollector
from torchrl.envs import TransformedEnv, InitTracker
from torchrl.envs import GymEnv
from torchrl.modules import MLP, LSTMModule
from torch import nn
from tensordict.nn import TensorDictSequential as Seq, TensorDictModule as Mod

env = TransformedEnv(GymEnv("Pendulum-v1"), InitTracker())
assert env.base_env.batch_locked
lstm_module = LSTMModule(
    input_size=env.observation_spec["observation"].shape[-1],
    hidden_size=64,
    in_keys=["observation", "rs_h", "rs_c"],
    out_keys=["intermediate", ("next", "rs_h"), ("next", "rs_c")])
mlp = MLP(num_cells=[64], out_features=1)
policy = Seq(lstm_module, Mod(mlp, in_keys=["intermediate"], out_keys=["action"]))
policy(env.reset())
env = env.append_transform(lstm_module.make_tensordict_primer())
data_collector = SyncDataCollector(
    env,
    policy,
    frames_per_batch=10
)
for data in data_collector:
    print(data)
    break

and the env is batch-locked. Can you give a runnable example perhaps?

ErcBunny · 2024-07-26T16:49:56Z

Thanks for the reply!

Sorry for mis-using the word "batch-locked", I meant vectorized environments with batch size larger than one.

My env is a derived env from EnvBase that creates Isaac Gym vectorized envs under the hood. I tried to use the wrapper but it failed to create the envs (#2292) so I decided to follow the tutorial to define a simple wrapper.

A rollout of 16 steps and 64 envs looks like this:

original_env = MyEnv(
    cfg=cfg_dict["task"],
    device=cfg["sim_device"],
    graphics_device_id=cfg["graphics_device_id"],
    headless=cfg["headless"],
    force_render=cfg["force_render"],
)
check_env_specs(env)

target_num_steps = 200
t0 = time.time()
with torch.no_grad():
    rollout_data = env.rollout(target_num_steps)
t1 = time.time()
print(rollout_data)

        next: TensorDict(
            fields={
                done: Tensor(shape=torch.Size([64, 16, 1]), device=cuda:0, dtype=torch.bool, is_shared=True),
                observation: TensorDict(

            device=cuda:0,

    batch_size=torch.Size([64, 16]),
    device=cuda:0,
    is_shared=True)

I also tried to modify your code with ParallelEnv:

from torchrl.collectors import SyncDataCollector
from torchrl.envs import TransformedEnv, InitTracker
from torchrl.envs import GymEnv
from torchrl.modules import MLP, LSTMModule
import torch
from tensordict.nn import TensorDictSequential as Seq, TensorDictModule as Mod
from torchrl.envs import ParallelEnv


def env_make():
    return GymEnv("Pendulum-v1")


env = TransformedEnv(ParallelEnv(3, env_make), InitTracker())
assert env.base_env.batch_locked

lstm_module = LSTMModule(
    input_size=env.observation_spec["observation"].shape[-1],
    hidden_size=64,
    in_keys=["observation", "rs_h", "rs_c"],
    out_keys=["intermediate", ("next", "rs_h"), ("next", "rs_c")],
)
mlp = MLP(num_cells=[64], out_features=1)
policy = Seq(lstm_module, Mod(mlp, in_keys=["intermediate"], out_keys=["action"]))
policy(env.reset())

env = env.append_transform(lstm_module.make_tensordict_primer())

data_collector = SyncDataCollector(env, policy, frames_per_batch=10)
for data in data_collector:
    print(data)
    break

but it gave me errors when executing env.reset():

RuntimeError: 
      An attempt has been made to start a new process before the

      This probably means that you are not using fork to start your
      child processes and you have forgotten to use the proper idiom
      in the main module:

          if __name__ == '__main__':
              freeze_support()
              ...

      The "freeze_support()" line can be omitted if the program
      is not going to be frozen to produce an executable.

Maybe I am not using parallel envs correctly... So I am afraid that I can't give you a running example, but I hope these tests can provide more info for the issue.

vmoens · 2024-07-28T09:47:59Z

Your rollouts looks ok to me.

The error you're seeing with ParallelEnv should be solved if you put it in a if __name__ == "__main__", like in this example where I wrap a Serial env (N=3) in a ParallelEnv (N=2):

from tensordict.nn import TensorDictSequential as Seq, TensorDictModule as Mod

from torchrl.collectors import SyncDataCollector
from torchrl.envs import GymEnv
from torchrl.envs import TransformedEnv, InitTracker, ParallelEnv, SerialEnv
from torchrl.modules import MLP, GRUModule


def make_env():
    return TransformedEnv(GymEnv("Pendulum-v1"), InitTracker())


if __name__ == "__main__":

    gru_module = GRUModule(
        input_size=make_env().observation_spec["observation"].shape[-1],
        hidden_size=64,
        in_keys=["observation", "rs"],
        out_keys=["intermediate", ("next", "rs")])
    mlp = MLP(num_cells=[64], out_features=1)
    policy = Seq(gru_module, Mod(mlp, in_keys=["intermediate"], out_keys=["action"]))
    primer = gru_module.make_tensordict_primer()
    env = ParallelEnv(2,
                      lambda primer=primer:
                      SerialEnv(3, make_env).append_transform(primer.clone()))
    reset = env.reset()
    print('reset', reset)
    policy(reset)
    print('reset after policy', reset)

    data_collector = SyncDataCollector(
        env,
        policy,
        frames_per_batch=10
    )
    for data in data_collector:
        print("data from rollout", data)
        break

Since I can't repro I'm closing this, but if you still encounter an error feel free to re-open

ErcBunny · 2024-07-28T10:07:14Z

Thx for the example. But I get errors and cannot complete the rollout. Is it because I am using version 0.4?

Could be! I'll make the 0.5 release soon (somewhere this week), let's see if it fixes it (you can also use nightlies to check!)

In v0.5, make_tensordict_primer no longer throws IndexError. Super nice!
