我在 tensorboard.py 和 tensorboard_handler.py 文件中清除了 python 2to3 的差异，但 Tensorboard 仍然存在可视化错误。

浏览器端错误：

图形可视化失败：错误：解析图形定义失败

服务器端错误日志是：

Exception happened during processing of request from ('127.0.0.1', 52783)

Traceback (most recent call last):

tensorboard_handler.py使用StringIO，但随后将字节传递给它。在使用 Python 3 时，可能应该使用它BytesIO（这是 Python 3 中的新功能）。这个问题是相关的：StringIO in python3。

不幸的是，Tensorboard 还不支持 python 3，但如果你碰巧解决了这个问题，请发送拉取请求。
