Failed testing with "RuntimeError: Graph is finalized and cannot be modified." #757

I tried to install baselines into my working environment but the testing failed. Working environment: Tensorflow 1.12.0, python 3.6, gym 0.10.9

Error information: def test_noise_normal():

  _run('--noise_type=normal_0.1')

Fixed. I changed my environment.

Not solved yet. I believe it can be ignored.
