[yujianyuanhaha]

OS: Ubuntu18.4
CNTK version 2.5
UE4Editor version: 4.17
Airsim version: 4.18
I finally successfully install the cntk on Ubuntu18.04, and hello_car.py also runs well, while met new issue of MemoryError when call the DQNcar.py, error shown as

/home/jet/anaconda3/envs/py2/lib/python2.7/site-packages/cntk/cntk_py_init.py:47: UserWarning: Unsupported Linux distribution (ubuntu-18.04). CNTK supports Ubuntu 16.04 and above, only.

Anybody got a idea?

Hi, I meet with the same issue, have you figured it out?

Hi, I meet with the same issue, have you figured it out?

nope. I later refer to some other open source code in github, tho older library

I have same issue also in DQNdrone.py

Is this related to #2226?

Well how big do you choose your replay buffer to be? I mean I can't fit 1 million samples in there as they did in the paper.

I can't say that either :-)
Seems to be trial and error (if this is causing the error)

possibly related to #1009

Hi, thank you for reporting this issue. This script was recently removed in #3215 and replaced with a new script at \AirSim\PythonClient\reinforcement_learning\dqn_car.py that uses the new OpenAI gym wrapper. I tested the new script locally and it runs for me. Can you retest with the new script and report back if you see any issues?
