我们从Python开源项目中，提取了以下3个代码示例，用于说明如何使用keras.callbacks.ProgbarLogger()。
def __init__(self, show_metrics=None): super(ProgbarLogger, self).__init__() self.show_metrics = show_metrics
def on_train_begin(self, logs=None): super(ProgbarLogger, self).on_train_begin(logs) if self.show_metrics: self.params['metrics'] = self.show_metrics
def __init__(self, n_classes, *args): super(Callback, self).__init__() # Save input parameters self.n_classes = n_classes self.I = np.zeros(self.n_classes) self.U = np.zeros(self.n_classes) self.jacc_percl = np.zeros(self.n_classes) self.val_I = np.zeros(self.n_classes) self.val_U = np.zeros(self.n_classes) self.val_jacc_percl = np.zeros(self.n_classes) self.remove_metrics = [] for i in range(n_classes): self.remove_metrics.append('I' + str(i)) self.remove_metrics.append('U' + str(i)) self.remove_metrics.append('val_I' + str(i)) self.remove_metrics.append('val_U' + str(i)) self.add_metrics = [] self.add_metrics.append('jaccard') self.add_metrics.append('val_jaccard') for i in range(n_classes): self.add_metrics.append(str(i) + '_jacc') self.add_metrics.append(str(i) + '_val_jacc') setattr(ProgbarLogger, 'add_metrics', self.add_metrics) setattr(ProgbarLogger, 'remove_metrics', self.remove_metrics) setattr(ProgbarLogger, '_set_params', progbar__set_params) setattr(ProgbarLogger, 'on_batch_end', progbar_on_batch_end) setattr(ProgbarLogger, 'on_epoch_end', progbar_on_epoch_end)
