cbfinn / maml_rl Goto Github PK

Hi,
I'd like to ask few important questions,

• is it possible to implement MAML with DDPG like other implemented MAML-RL algorithms?
• if so, what are the right way to do that? and how much we expect the DDPG performance will improve after adding MAML?

regards,

Hi, I try to run the code. Last day, I success. But today I meet a strange problem.
I don't modify any code, just use setup_mujoco.sh script from
to setup the mujoco env for running cluster_trpo_cheetah.py:
For bug information see:

It seems that the VG class init with 4 arguments but default init is 2. But I check the class VariantGenerator, it's init with no arguments. So with this bug information I can't locate where the problem is. Have you ever meet this problem.

Here is my Error:

Traceback (most recent call last):
  File "maml_examples/cluster_maml_trpo_ant.py", line 1, in <module>
    from sandbox.rocky.tf.algos.maml_trpo import MAMLTRPO
ImportError: No module named 'sandbox.rocky.tf.algos.maml_trpo'

I have installed rllab3 , and set PYTHONPATH properly.
then source activate rllab3 , go to maml_rl directory and run python maml_examples/cluster_maml_trpo_ant.py , and this error occurs.
What's wrong? should I git clone maml_rl into some directory under rllab?

Hi,
I'm trying to set up the environment with Anaconda to run the code.
I'm running: conda env create -f environment.yml and I get error:

Warning: you have pip-installed dependencies in your environment file, but you do not list pip itself as one of your conda dependencies.  Conda may not use the correct pip to install your packages, and they may end up in the wrong place.  Please add an explicit pip dependency.  I'm adding one for you, but still nagging you.
Collecting package metadata (repodata.json): done
Solving environment: failed

ResolvePackageNotFound:
  - joblib==0.9.4
  - numpy==1.10.4
  - python==3.5.2

Do you know how to fix that?

when I run test_maml_cheetah.py cause OSerror:
OSError: ../vendor/mujoco/libmujoco131.so: cannot open shared object file: No such file or directory
can you append the need part?

thank you!

Hi, I run ./scripts/setup_linux.sh and get the following error:

Creating conda environment...

I have tried many times and the error always occurs. I wonder whether the version you used can not work now ? or other problems.
Thanks.

Hello,
I am trying to set up Mujoco for one of my projects. I installed all the dependencies and used the appropriate license file. When I am trying to run test_maml_ant.py, its giving me the following error

func = self._FuncPtr((name_or_ordinal, self))
AttributeError: function 'mjv_makeObjects' not found

in the file mjlib.py. Does anyone know if it is the installation issue or am I missing something? The examples provided by the mujoco_py repositories are working without any error though.

Hello! I'm wondering if there are any good reasons for adding self.get_body_com("torso").flat to the observations of half cheetah:

Hi, I've been trying to replicate some of your results and compare against Reptile, for the reinforcement learning case. Specifically, I'm trying to run the point mass experiments.

After installing everything and sourcing the conda env rllab3 and running python maml_examples/maml_trpo_point.py, it complains about Theano and Lasagne not being installed.

From the README, it seems like this was built on the Tensorflow version of rllab. Does it still need Theano or am I doing something wrong?

PS: Thanks for open-sourcing your work!

Hello,

I'm trying to implement the maml_rl for PyTorch, while I couldn't find where you fit the baseline.
Can you help me point it out?
