failed to check the installation with mujoco envs

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

I got the following errors:

@pxlong oh geez this tensorflow bug is fun. what version of tensorflow are you using?

The root of the error is here

dlopen: cannot load any more object with static TLS.

It turns out tensorflow allocates a bunch of limited resources normally shared by dynamically loaded libraries, so it’s sometimes possible to run out of them if tensorflow is loaded too late. Importing tensorflow earlier in the load process seems to fix the problem.

If you want to read about the bug here’s the thread https://github.com/tensorflow/tensorflow/issues/19010#issuecomment-386846086

Other solutions include updating to a more recent ubuntu or increasing the number of TLS slots.

I will update my OS to 16.04 and test it again. Many thx.
