如何合并两个tensorflow事件文件，或者让tensorflow以相同的颜色绘制它们？

import tensorflow as tf
from tensorboard.backend.event_processing import event_accumulator

merged_file = 'merged_events.tf'
summary_writer = tf.summary.FileWriter(merged_file)

event_file1 = 'events1.tf'
event_file2 = 'events2.tf'
ea1 = event_accumulator.EventAccumulator(event_file1)
ea1.Reload()
ea2 = event_accumulator.EventAccumulator(event_file2)
ea2.Reload()

# 获取事件文件1的标签
tags1 = ea1.Tags()['scalars']

# 将事件文件1的标签添加到新的事件文件中
for tag in tags1:
    events1 = ea1.Scalars(tag)
    for event in events1:
        summary = tf.Summary(value=[tf.Summary.Value(tag=event.tag, simple_value=event.value)])
        summary_writer.add_summary(summary, global_step=event.step)

# 获取事件文件2的标签
tags2 = ea2.Tags()['scalars']

# 将事件文件2的标签添加到新的事件文件中
for tag in tags2:
    events2 = ea2.Scalars(tag)
    for event in events2:
        summary = tf.Summary(value=[tf.Summary.Value(tag=event.tag, simple_value=event.value)])
        summary_writer.add_summary(summary, global_step=event.step)

summary_writer.close()
