OpenAI gym 0.10.9 'module' object has no attribute 'benchmark_spec'
benchmark = gym.benchmark_spec('Atari40M') 

AttributeError: 'module' object has no attribute 'benchmark_spec'

I just got this error for gym-0.10.9. Any idea? Thx

According to this post on GitHub, the function 'benchmark_spec' is no longer supported.
