Implement anything that needs to happen after every step :return:

>>> _isint("123") True >>> _isint("123.45") False

>>> _isnumber("123.45") True >>> _isnumber("123") True >>> _isnumber("spam") False

Returns a function that maps each index in 0, 1, ..., n-1 to a distinct RGB color; the keyword argument name must be a standard mpl colormap name.

Open a file; if filename ends with .gz, opens as a gzip file

Perform one timestep of the environment's dynamic. "send_action" and "get_result" are coupled in sync simulation, so typically users o

Unnormalize observations by statistics in obs_rms.

Unpickle data from file specified by filename.

Implements returning and environment corresponding to given task params

Fetch a list of env attributes. This function tries to retrieve an attribute from each individual wrapped environment, if it does not

:param env: Env. :param qf: QFunction. Maps from state to action Q-values. :param learning_rate: Learning rate for qf. Adam

Symbols after a decimal point, -1 if the string lacks the decimal point. >>> _afterpoint("123.45") 2 >>> _afterpoint("1001") -1 >

[string] -> [padded_string] >>> list(map(str,_align_column(["12.345", "-1234.5", "1.23", "1234.5", "1e+234", "1.0e234"], "decimal"))) [' 12

Train the discriminator

Perform some update, e.g. perform one gradient step. :return:

Format a value accoding to its type. Unicode is supported: >>> hrow = ['\u0431\u0443\u043a\u0432\u0430', '\u0446\u0438\u0444\u0440\u0430'] ;

Produce a plain-text representation of the table.

Get an action to take in the environment. :param observation: :return:

Get an action to take in the environment. :param observation: :return:

Get an action to take in the environment. :param observation: :return:

Naive implementation: just loop through each transition. :param path: :return:

Transform a supported data type to a list of lists, and a list of headers. Supported tabular data types: * list-of-lists or another iterable

Center string. >>> _padboth(6, '\u044f\u0439\u0446\u0430') == ' \u044f\u0439\u0446\u0430 ' True

Flush right. >>> _padleft(6, '\u044f\u0439\u0446\u0430') == ' \u044f\u0439\u0446\u0430' True

Return a segment of a horizontal line with optional colons which indicate column's alignment (as in `pipe` output format).

The least generic type (type(None), int, float, str, unicode). >>> _type(None) is type(None) True >>> _type("foo") is type("") True
