Re: [apache/incubator-tvm] [RFC] Add TVMDSOOp to integrate any TVM operator with TensorFlow (#4464)

[652994331 <no...@github.com>]

@tobegit3hub Hi guys, i built tvm before and i built tvmsoop separately(not from USE_TF_TVMSOOP=ON) follow this:https://github.com/tobegit3hub/tftvm/tree/master/examples .
After i got libxx.so and link them to my tvm home, i run the test

import tensorflow as tf
from tvm.contrib import tf_op

mod = tf_op.Module("tvm_addone_dll.so")
addone = mod.func("addone", output_shape=[4])

with tf.Session() as sess:
  a = tf.constant([10.1, 20.0, 11.2, -30.3])
  b = addone(a)
  print(sess.run(b))


and i got this error:
Traceback (most recent call last):
  File "test_python.py", line 5, in <module>
    addone = mod.func("add_one, output_shape=[4]")
  File "/opt/cephfs1/asr/users/qizhou.huang/.local/lib/python3.6/site-packages/tvm-0.7.dev1-py3.6-linux-x86_64.egg/tvm/contrib/tf_op/module.py", line 27, in func

my gcc is 6.4.0,my tensorflow flow is tf-1.15.0 i use bazel build it from source and set -D_GLIBCXX_CXX11_ABI=1. 
Btw, i also tried the pip install tensorflow,-1.13.1, same error. Couild you please help me out, thanks
