optuna.trial.TrialState
- class optuna.trial.TrialState(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)[source]
State of a
Trial
.- PRUNED
The
Trial
has been pruned withTrialPruned
.
Methods
Return a bool value to represent whether the trial state is unfinished or not.
Return integer ratio.
Number of ones in the binary representation of the absolute value of self.
Number of bits necessary to represent self in binary.
Returns self, the complex conjugate of any int.
from_bytes
([byteorder, signed])Return the integer represented by the given array of bytes.
to_bytes
([length, byteorder, signed])Return an array of bytes representing an integer.
Attributes
the denominator of a rational number in lowest terms
the imaginary part of a complex number
the numerator of a rational number in lowest terms
the real part of a complex number
- as_integer_ratio()
Return integer ratio.
Return a pair of integers, whose ratio is exactly equal to the original int and with a positive denominator.
>>> (10).as_integer_ratio() (10, 1) >>> (-10).as_integer_ratio() (-10, 1) >>> (0).as_integer_ratio() (0, 1)
- bit_count()
Number of ones in the binary representation of the absolute value of self.
Also known as the population count.
>>> bin(13) '0b1101' >>> (13).bit_count() 3
- bit_length()
Number of bits necessary to represent self in binary.
>>> bin(37) '0b100101' >>> (37).bit_length() 6
- conjugate()
Returns self, the complex conjugate of any int.
- denominator
the denominator of a rational number in lowest terms
- from_bytes(byteorder='big', *, signed=False)
Return the integer represented by the given array of bytes.
- bytes
Holds the array of bytes to convert. The argument must either support the buffer protocol or be an iterable object producing bytes. Bytes and bytearray are examples of built-in objects that support the buffer protocol.
- byteorder
The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use `sys.byteorder’ as the byte order value. Default is to use ‘big’.
- signed
Indicates whether two’s complement is used to represent the integer.
- imag
the imaginary part of a complex number
- is_finished()[source]
Return a bool value to represent whether the trial state is unfinished or not.
The unfinished state is either
RUNNING
orWAITING
.- Return type:
- numerator
the numerator of a rational number in lowest terms
- real
the real part of a complex number
- to_bytes(length=1, byteorder='big', *, signed=False)
Return an array of bytes representing an integer.
- length
Length of bytes object to use. An OverflowError is raised if the integer is not representable with the given number of bytes. Default is length 1.
- byteorder
The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use `sys.byteorder’ as the byte order value. Default is to use ‘big’.
- signed
Determines whether two’s complement is used to represent the integer. If signed is False and a negative integer is given, an OverflowError is raised.
