Python中numpy.array方法典型示例

Python中numpy.array方法的典型用法示例: 以下的两个例子应该可以给你带来一些思路

示例1: __init__

# 需要导入模块: import numpy [as 别名]
# 或者: from numpy import array [as 别名]
def __init__(self, input_wave_file, output_wave_file, target_phrase):
        self.pop_size = 100
        self.elite_size = 10
        self.mutation_p = 0.005
        self.noise_stdev = 40
        self.noise_threshold = 1
        self.mu = 0.9
        self.alpha = 0.001
        self.max_iters = 3000
        self.num_points_estimate = 100
        self.delta_for_gradient = 100
        self.delta_for_perturbation = 1e3
        self.input_audio = load_wav(input_wave_file).astype(np.float32)
        self.pop = np.expand_dims(self.input_audio, axis=0)
        self.pop = np.tile(self.pop, (self.pop_size, 1))
        self.output_wave_file = output_wave_file
        self.target_phrase = target_phrase
        self.funcs = self.setup_graph(self.pop, np.array([toks.index(x) for x in target_phrase])) 

示例2: create_lines

# 需要导入模块: import numpy [as 别名]
# 或者: from numpy import array [as 别名]
def create_lines(self, x, varieties):
        """
        Draw just the data portion.
        """
        lines = pd.DataFrame()
        for i, var in enumerate(varieties):
            self.legend.append(var)
            data = varieties[var]["data"]
            color = get_color(varieties[var], i)
            x_array = np.array(x)
            y_array = np.array(data)
            line = pd.DataFrame({"x": x_array,
                                 "y": y_array,
                                 "color": color,
                                 "var": var})
            lines = lines.append(line, ignore_index=True, sort=False)
        return lines
