如何使用Dart HttpClient进行DELETE请求？(How can DELETE requests be made with a Dart HttpClient?)

 有两种可能的解决方法来解决错误： 
 
 不要导入batch_norm 
 
 只需在代码中直接使用tf.contrib.layers.python.layers.batch_norm ，从而省略import语句（不可否认，会造成很多混乱）。 
 
 设置环境变量LD_PRELOAD 
 
 dennybritz在2月10日发布的github问题中提供了以下修复： 
 
sudo apt-get install libtcmalloc-minimal4
export LD_PRELOAD="/usr/lib/libtcmalloc_minimal.so.4"
 
 请注意，如果您使用的是PyCharm，则必须在运行配置中指定此环境变量（请参阅此文章 ），或者如果将上述export语句放入.bashrc ，则必须从命令行启动PyCharm它继承了环境变量（如本文所述）。 
 
 然而，虽然这解决了这个问题，但我不知道为什么首先出现这个错误，并且它应该被认为是应该报告给tensorflow或numpy-quaternion开发人员的错误。 

There are two possible ways to work around/fix the error:
 
Don't import batch_norm
 
Just always use tf.contrib.layers.python.layers.batch_norm directly in the code, thus omitting the import statement (admittedly, creates a lot of clutter).
 
Set environment variable LD_PRELOAD
 
The following fix posted by dennybritz on February 10th in this github issue helped:
 
sudo apt-get install libtcmalloc-minimal4
export LD_PRELOAD="/usr/lib/libtcmalloc_minimal.so.4"
 
Note that if you're using PyCharm, you either have to specify this environment variable in the run configurations (see this post) or - if you put the above export statement into your .bashrc - you have to start PyCharm from the command line so that it inherits the environment variables (as explained in this post).
 
However, while this fixes the issue, I don't know why this error occurs in the first place and if it should be considered a bug that should be reported to either tensorflow or numpy-quaternion devs.
