For people who are on windows 10 and do not have linux but want to make things work.

1. you can enable the WSL in your windows 10 following this.
2. Install Xming X window server for windows from here. and make sure it is running.
3. Once WSL is working : Open cmd, type in "bash", this will switch the cmd to WSL terminal, then run the following it will enable GUI for WSL . Copied from this stackoverflow answer.

    sudo apt-get install x11-apps
    export DISPLAY=localhost:0.0 
    nano ~/.bashrc  #(add  export DISPLAY=localhost:0.0   at the end. Ctrl+X to exit/save)
    sudo apt-get install gnome-calculator #will get you GTK

4. Download miniconda for linux from here. It will be an ".sh" file.
5. from the terminal go to the folder you downloaded the file to and run "bash <name_of_downloaded_file>", this will install conda.
6. follow the spinningup tutorial for rest of installation.

Followed Mujoco install, followed by full Gym installation.

Used Miniconda, py 3.6

On fresh OSX Mojave (right out of the box!)

Ran the following code:

import gym
import tensorflow as tf
from spinup import ddpg

env_name = 'Pendulum-v0'
env_fn       = lambda : gym.make(env_name)

ac_kwargs = {
        'hidden_sizes':[64,64], 
        'activation'  :tf.nn.relu
    }

logger_kwargs = {
    'output_dir'  : 'logs', 
    'exp_name'  :'pendulum_test'
    }

addl_kwargs = {
    'seed' : 42
}

ddpg(env_fn, ac_kwargs=ac_kwargs, logger_kwargs=logger_kwargs, **addl_kwargs)

Received following error on first build:

INFO:tensorflow:Assets added to graph. INFO:tensorflow:No assets to write. INFO:tensorflow:SavedModel written to: logs/simple_save/saved_model.pb

OMP: Error #15: Initializing libiomp5.dylib, but found libiomp5.dylib already initialized.

OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into theprogram. That is dangerous, since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results. For more information, please see http://www.intel.com/software/products/support/.

The workaround is including:

os.environ['KMP_DUPLICATE_LIB_OK']='True'

However, is there a more permanent fix? Why might there be multiple instances of OpenMP?

As a heads up some users might run into the following error when attempting to plot the performance of their agent when checking their installation the first time:

ImportError: Python is not installed as a framework. The Mac OS X backend will not be able to function correctly if Python is not installed as a framework. See the Python documentation for more information on installing Python as a framework on Mac OS X. Please either reinstall Python as a framework, or try one of the other backends. If you are using (Ana)Conda please install python.app and replace the use of 'python' with 'pythonw'. See 'Working with Matplotlib on OSX' in the Matplotlib FAQ for more information.

In order to overcome this, they can follow the steps outlined here

I have no clue if this only happens in a virtual environment (I was personally using a Conda environment) and didn't know where else to put it. Hope this helps!

Having the code base in some dynamic graph style library would be great. Pytorch does this well, but since google has released eager execution, having the codebase in eager execution mode will be really nice to have since the codebase is a learning tool. I was having a bit of trouble understanding the session based control of tensorflow (coming from a pytorch background) for the vanilla policy gradient, inspite of it being written really well :')

I would be happy to slowly convert some of the codebase to support eager execution. Do you think this would be useful ?

I am installing Spinning Up on Mac OS. I followed this link After this, to see if you’ve successfully installed Spinning Up, I tried running PPO in the LunarLander-v2 environment with python -m spinup.run ppo --hid "[32,32]" --env LunarLander-v2 --exp_name installtest --gamma 0.999 Then an error pops up

I have no idea about this error. Can anyone give me help?

Hi,

I've tried spinningup in running many experiments using the different algorithms in different Gym environments. It works well in most environments, like Atari, Box2D, Classic control and MuJoCo, however it didn't work with the new gym environments of "Robotics".

For example when I run the following command on terminal: python -m spinup.run ppo --env FetchReach-v1 --exp_name FetchReach

It shows:

================================================================================

Does SpinningUp support this enviroments (Robotics) or it is a problem from my side?

I'm using Ubuntu 14.04 + Python 3.6.7 (Anaconda3-5.3.0-Linux-x86_64).

I have successfully installed mujoco, mujoco_py, gym and spinningup.

mujoco                    150
mujoco-py                 1.50.1.68
gym                       0.10.9 
spinup                    0.1

And the following code could work:

env = gym.make('Humanoid-v2') 
env.reset() 
env.render() 

But when I checked the spinningup installation by:

python -m spinup.run ppo --hid [32,32] --env Walker2d-v2 --exp_name installtest

Hi Everyone! I work in a PyCharm environment over Ubuntu 18.04 when I try to execute a variation on this command:

python -m spinup.run sac --hid "[32,32]" --env LunarLander-v2 --exp_name installtest --gamma 0.999

variation means I've tried different combinations of --env, with/without --gamma with/without --hid and its always the next Error Callstack

Line 259 in ppo.py, buf.store(o,a,r,v_t,logp_t) At the first step in every epoch, we set r=0. So the operation in line 259 results that the first record of reward in the rew_buf is always 0. In fact, we should record the reward after executing pi in the first state.
The operation above causes the problems in the function finish_path. In line62 and line 66, the first record in the rew_buf may result some problems and leave out the last reward during the end of every epoch. To solve this problems, I change the code slightly as below: line262: o_, r, d, =env.step(a[0]) line263: buf.store(o, a, r, v_t, logp_t) line264: ep_ret+ = r line265: ep_len+ = 1 line266: o = o After changing these codes, I also change: line 58: rews = self.rew_buf[path_slice] line 62: deltas=rews + self.gamma * vals[1:] - vals[:-1] line 66:self.ret_buf[path_slice] = core.discount_cumsum(rews, self.gamma)

I don't know whether I am wrong. I am sincerely hoping that you can answer my question. Thank you!

@jachiam Hi! It's me again! 2 days ago I posted an issue on using multiple cpu on ExperimentGrid that seems to only give the wrong log when run in Pycharm but fine in terminal. I did some more experiments today, and found that although when run from terminal, the log seems to be correct, but there could still be a bug, the proof is that a multi-cpu run will always use more time compared to single cpu run, when solving the same number of jobs.

Here is the code I tried, when you have time, could you try run it and see if you can reproduce the bug? My machine has 4 cores, and using 2 cores to run 4 jobs should be faster than using 1 core to run 4 jobs. The result I get is: single-cpu about 15 seconds, multi-cpu about 20 seconds. I have run this code from terminal, the result indicates that with the same number of jobs, multi-cpu uses more time than single-cpu, which seems a bug to me. I believe what the code might be doing is that for every variant, the same variant has been run num_cpu times.

from spinup.utils.run_utils import ExperimentGrid
from spinup import ppo

import time
if __name__ == '__main__':
    total_num_runs = 4
    import argparse

    ## try multi-cpu case
    parser = argparse.ArgumentParser()
    parser.add_argument('--cpu', type=int, default=2)
    parser.add_argument('--num_runs', type=int, default=total_num_runs)
    args = parser.parse_args()

    ## reset timing
    starttime = time.time()
    eg = ExperimentGrid(name='ppo-bench')
    eg.add('env_name', 'CartPole-v0', '', True)
    eg.add('seed', [10 * i for i in range(args.num_runs)])
    eg.add('epochs', 1)
    eg.add('steps_per_epoch', 200)
    eg.run(ppo, num_cpu=args.cpu)
    multi_cpu_time = time.time() - starttime

    ## try single-cpu case
    args.cpu = 1

    ## reset timing
    starttime = time.time()
    eg = ExperimentGrid(name='ppo-bench')
    eg.add('env_name', 'CartPole-v0', '', True)
    eg.add('seed', [10 * i for i in range(args.num_runs)])
    eg.add('epochs', 1)
    eg.add('steps_per_epoch', 200)
    eg.run(ppo, num_cpu=args.cpu)
    single_cpu_time = time.time() - starttime

    print('single-cpu',single_cpu_time,'multi-cpu',multi_cpu_time)

Many thanks!

I am trying to install as specifies in the docs: git clone https://github.com/openai/spinningup.git cd spinningup pip install -e . and I am getting this error: ERROR: Could not find a version that satisfies the requirement tensorflow<2.0,>=1.8.0 (from spinup) (from versions: 2.2.0, 2.2.1, 2.2.2, 2.2.3, 2.3.0, 2.3.1, 2.3.2, 2.3.3, 2.3.4, 2.4.0, 2.4.1, 2.4.2, 2.4.3, 2.4.4, 2.5.0, 2.5.1, 2.5.2, 2.5.3, 2.6.0rc0, 2.6.0rc1, 2.6.0rc2, 2.6.0, 2.6.1, 2.6.2, 2.6.3, 2.6.4, 2.6.5, 2.7.0rc0, 2.7.0rc1, 2.7.0, 2.7.1, 2.7.2, 2.7.3, 2.7.4, 2.8.0rc0, 2.8.0rc1, 2.8.0, 2.8.1, 2.8.2, 2.8.3, 2.8.4, 2.9.0rc0, 2.9.0rc1, 2.9.0rc2, 2.9.0, 2.9.1, 2.9.2, 2.9.3, 2.10.0rc0, 2.10.0rc1, 2.10.0rc2, 2.10.0rc3, 2.10.0, 2.10.1, 2.11.0rc0, 2.11.0rc1, 2.11.0rc2, 2.11.0) ERROR: No matching distribution found for tensorflow<2.0,>=1.8.0

I tried installing tensorflow but the only installation I could use is 2.2... Does that mean that I need to find a 1.8 tensorflow installation?

Thank you

Don't know if this has been detailed before, but I have gotten spinningup to work on WSL2 on windows without needing to install a X server for X11 forwarding. If you didn't know, WSL2 has WSLg which allows for you to run GUI apps in WSL.

First make sure you have WSL2 enabled in your system, you can check by using: wsl -l -v in cmd/powershell. To upgrade to WSL2, issue the command wsl --set-version <distro name> 2 replacing <distro name> with the name of the distribution you want to upgrade.

Next, install the vGPU driver for Ubuntu by following this link here. At the time of this post, the cuda version was 11.8, this will be important later on.

Install miniconda by downloading the .sh from here. Personally, I use pyenv which you can check out here. If you run into any dependency issues creating your virtualenv you might need to find one with python=3.6 support.

Follow spinningup for the rest of the installation.

Here is where we need to potentially fix things. If you encounter no errors, then maybe the issues were patched out. However, when trying to watch the trained policy you might encounter this error:

ImportError:
    Error occurred while running `from pyglet.gl import *`
    HINT: make sure you have OpenGL install. On Ubuntu, you can run 'apt-get install python-opengl'.
    If you're running on a server, you may need a virtual frame buffer; something like this should work:
    'xvfb-run -s "-screen 0 1400x900x24" python <your_script.py>'

To fix this issue, install an OpenGL library. The python-opengl library may not be present in your Ubuntu WSL distro, but you can install sudo apt install freeglut3-dev

You might also encounter another error:

libGL error: MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
libGL error: failed to load driver: swrast

Most likely this is due to the anaconda/miniconda install having too old of an GLIBCXX binary (even if your system has a new one). We can check this by exporting this variable: export LIBGL_DEBUG=verbose and running the command again. If we see:

libGL: MESA-LOADER: failed to open /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so: /home/dev/.pyenv/versions/miniconda3-latest/envs/su/bin/../lib/libstdc++.so.6: version `GLIBCXX_3.4.30' not found (required by /lib/x86_64-linux-gnu/libLLVM-13.so.1)

Then we can fix this by symlinking our systems GLIBCXX to conda distribution by executing:

ln -s -f /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.30 $CONDA_PREFIX/lib/libstdc++.so.6

If everything works you should see the training video when running the command again.

Hi,

going through the RL Intro I stumbled something that is not yet clear to me. On https://spinningup.openai.com/en/latest/spinningup/rl_intro.html#the-rl-problem for the expected return it says .. math:: J(\pi) = \int_{\tau} P(\tau|\pi) R(\tau) = \underE{\tau\sim \pi}{R(\tau)} where I would have expected .. math:: J(\pi) = \int_{\tau} P(\tau|\pi) R(\tau) = \underE{\tau\sim P}{R(\tau)}

My understanding is that \tau is a RV distributed with respect to P, and only the actions are taken from \pi, as later clearly differentiated on https://spinningup.openai.com/en/latest/spinningup/rl_intro.html#bellman-equations

Please, can someone explain me why it says \tau\sim \pi?

Thank you very much in advance!

rllib moved from this directory to this directory, but almost all of the references in the documentation refer to the old link. (for instance: in the section Why We Built This

Please update the same.

Actually, the changed link references https://spinningup.openai.com/en/latest/spinningup/rl_intro3.html#id16 and not https://spinningup.openai.com/en/latest/spinningup/extra_pg_proof1.html
