libtensorflow_framework so cannot open shared object file: no such file or directory
I just updated tensorflow with pip3 (now to version 1.4.1). After it I am having problems:
I have a custom op library that I compile with -D _GLIBCXX_USE_CXX11_ABI=0. The library compiles and links fine. Importing it into tensorflow gives:
Traceback (most recent call last): ... File "../x.py", line 29, in <module> lib = tf.load_op_library(_lib_path) File "/home/ilge/.local/lib/python3.5/site-packages/tensorflow/python/framework/load_library.py", line 56, in load_op_library lib_handle = py_tf.TF_LoadLibrary(library_filename, status) File "/home/ilge/.local/lib/python3.5/site-packages/tensorflow/python/framework/errors_impl.py", line 473, in __exit__ c_api.TF_GetCode(self.status.status)) tensorflow.python.framework.errors_impl.NotFoundError: /path/to/mylib.so: undefined symbol: _ZTIN10tensorflow8OpKernelE
It seems it cannot load general tensorflow symbols. Hints on how I could debug it are very appreciated. Note that before the update and before recompiling everything was working.
I was compiling and linking in two different steps in my make file, and just using the proper link flags when linking wasn't enough. I also had to pass the argument
-Wl,--no-as-needed to the linker, because for some reason gcc was discarding the library in the final module (as shown by ldd).
So my Makefile looks like this
TF_CFLAGS:=$(shell python -c 'import tensorflow as tf; print(" ".join(tf.sysconfig.get_compile_flags()))') TF_LFLAGS:=$(shell python -c 'import tensorflow as tf; print(" ".join(tf.sysconfig.get_link_flags()))') all: myop_ops.so %.o: %.cc g++ -fPIC $(TF_CFLAGS) -O2 -std=c++11 -I/usr/local/include -c $< -o $@ myop_ops.so: myfile1.o myfile2.o myop_kernel.o myop_ops.o g++ -shared -Wl,--no-as-needed $(TF_LFLAGS) -o $@ $^

There can be a compatibility issue between the tensorflow and gcc versions. Check the version of gcc that tensorflow uses for building and use that version of gcc to compile your custom op library. For e.g. I installed tensorflow 1.6.0 with Anaconda2 and it uses gcc version 7.2. So I kept getting the same error as you when I compiled custom ops with gcc 4.8/4.9/5.3. Finally, I tried with gcc 7.3 and it worked.
