【问题描述】：

我在使用 skflow 在张量板上显示损失（训练或监控）摘要时遇到问题

这是我的代码：

classifier = skflow.TensorFlowEstimator(  model_fn=conv_model, n_classes=2, batch_size=BATCH_SIZE, steps=100000, learning_rate=0.001, config=RunConfig(gpu_memory_fraction=0.9))

val_monitor = monitors.ValidationMonitor(X_val, y_val, n_classes=2, print_steps=100)

classifier.fit(X_train, y_train, val_monitor, logdir='my_model_1/')

classifier.save('my_model_1/')

一切顺利：

它生成大小为 4,8M 的文件 .tfevents（附加）

当我使用 chrome 作为资源管理器连接到机器时，我在图形/直方图/中有数据，但在事件中没有任何数据（未找到标量数据）

我是否错过了记录丢失的内容？

注意：我添加了 logging_ops.scalar_summary("model_loss", self._model_loss) 在 learn/python/learn/estimators/base.py 中，模型损失出现在 tensorboard 中

Ps：我在 GPU 机器上运行使用最后一个构建 tensorflow 附tfeventsmy_model_1.zip
