Question

我已经使用bazel从源代码安装了tensorflow。但是当我在python中导入tensorflow时，会发生错误。

>>> import tensorflow as tf

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/zjuese/anaconda2/lib/python2.7/site-packages/tensorflow/__init__.py", line 8, in <module>
    from tensorflow.python import *
  File "/home/zjuese/anaconda2/lib/python2.7/site-packages/tensorflow/python/__init__.py", line 34, in <module>
    from tensorflow.python.client.client_lib import *
  File "/home/zjuese/anaconda2/lib/python2.7/site-packages/tensorflow/python/client/client_lib.py", line 39, in <module> 
    from tensorflow.python.client.session import InteractiveSession
  File "/home/zjuese/anaconda2/lib/python2.7/site-packages/tensorflow/python/client/session.py", line 16, in <module>
    from tensorflow.python import pywrap_tensorflow as tf_session
  File "/home/zjuese/anaconda2/lib/python2.7/site-packages/tensorflow/python/pywrap_tensorflow.py", line 26, in <module>
    _pywrap_tensorflow = swig_import_helper()
  File "/home/zjuese/anaconda2/lib/python2.7/site-packages/tensorflow/python/pywrap_tensorflow.py", line 22, in swig_import_helper
    _mod = imp.load_module('_pywrap_tensorflow', fp, pathname, description)
ImportError: /home/zjuese/anaconda2/lib/python2.7/site-packages/tensorflow/python/_pywrap_tensorflow.so: undefined symbol: clock_gettime

我现在该如何解决？

尝试在链接步骤中添加rt库，就像在这个diff：

中一样

--- a/tensorflow/tensorflow.bzl
+++ b/tensorflow/tensorflow.bzl
@@ -284,7 +284,7 @@ _py_wrap_cc = rule(attrs={

 def tf_extension_linkopts():
-  return []  # No extension link opts
+  return ["-lrt"]

另见github issue。

未定义的符号：在ubuntu14.04上具有tensorflow的clock_gettime
