Keras详细的培训进度条在每个批次问题上写一个新行

在Keras中运行密集的前馈神经网络。有两个输出的class_weights，第三个输出有sample_weights。出于某种原因，它会打印每个计算批次的进度详细显示，并且不会更新与其应该在同一行上的打印... 这是否发生过？它是如何修复的？从贝：Keras详细的培训进度条在每个批次问题上写一个新行

请添加更多详情 – Enn

@Enn，增加了一些信息。帮助？ –

我在Ubuntu 16.04上遇到了同样的问题，但在macOS 10.13上没有问题。 Haven没有找到解决方案。 – McLawrence

我也有类似的问题，但还没有进一步研究它的时候。这个问题似乎与keras的generic_utils.py中的Progbar类有关，参见link，也许Python> = 3.3。

107行：：

以下线路中的类的更新功能被发现sys.stdout.write('\b' * prev_total_width)
线108：sys.stdout.write('\r')

我简单地去除线107作为一个快速解决，所以不是退格的上一行然后执行转移到行的开头，我只执行转移。我想有比改变源代码更好的方法。

@fchollet，有什么想法？ –

这似乎是Keras一致的问题。我试图找到该行

sys.stdout.write('\b' * prev_total_width)

sys.stdout.write('\r')

在Keras/utils的/ generic_utils.py文件，他们是（以当前版本），在258和259相应。我评论258，但这似乎不能解决问题。我还是设法通过注释行，使进度条工作：

行303：sys.stdout.write(info)

它看来，如果信息使得杆过长，终端，因此它打破了一个新的生产线。

所以我最终解决了这个问题。现在看来似乎是在年底相当简单....

就使得终端更宽......

注：在测试了Linux操作系统Ubuntu 16.04 | Keras版本2.0.5

之前已经提到过，但我会将其重写为对未来用户更明显。

你有太窄终端打印所有这些值秒 - 只是设置参数的构造函数的Progbarwidth到数量较少或删除/重命名一些提供的值。
