visualDL如何查看网络结构graph？报错：malloc_error_break
Created by: my777777
按照READEME.md的Quick Start安装visualDL，无法查看graph 依次运行以下命令：
pip install --upgrade visualdl vdl_create_scratch_log visualdl --logdir=scratch_log -m scratch_log/mnist_model.onnx
在浏览器中点击『GRAPHS』后出现error，信息如下：
Python(6095,0x700007183000) malloc: *** error for object 0x7fce77307718: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug Abort trap: 6
版本信息如下： Mac: 10.13 Python: 2.7.16 visualDL: 1.3.0
