/usr/bin/ld: cannot find -ltensorflow_framework

[apple55bc]

I search the tensorflow path with :
python3

print(tf.sysconfig.get_lib())
/usr/local/lib/python3.5/site-packages/tensorflow
and add it by:
export TENSORFLOW_SRC_PATH=/usr/local/lib/python3.5/site-packages/tensorflow
source ~./bashrc

then i run:
python3 setup.py install

[root@cdsw1 tensorflow_binding]# python3 setup.py install

i just create a ln file to /usr/bin/ via:
ln -s /usr/local/python36/lib/python3.5/site-packages/tensorflow/libtensorflow_framework.so /usr/lib/libtensorflow_framework.so
and it seems work.

but i got another Error when i run test, this page show the Error and solved my second error:
#132

Unfortunately, then i got a third Error... I am trying to solve that:
ImportError: Failed to import test module: test_warpctc_op

Last error doesn't matter because I can still run wrap_ctc in my own code.

but there is still a error when I train my data using:

import warpctc_tensorflow
labels = tf.reshape(tf.sparse_tensor_to_dense(labels), shape=[-1,])
self.main_loss = warpctc_tensorflow.ctc(activations=chars_logit,
flat_labels=labels,
label_lengths=self.seq_targets_length,
input_lengths=self.seq_inputs_length,
blank_label=self._w2i_target["_EOS"]
)

when the num of label is 109, it got error:
tensorflow.python.framework.errors_impl.InvalidArgumentError: tags and values not the same shape: [] != [32] (tag 'totle_loss')
[[node totle_loss (defined at ocr_train.py:115) ]]

when I use another data witch has 4000+ labels, it got error:
CancelledError (see above for traceback): Loop execution was cancelled.
[[node gradients/b_count_2 (defined at ocr_train.py:106) ]]

I get no idea....

but when I use the following code:
with tf.get_default_graph()._kernel_label_map({"CTCLoss": "WarpCTC"}):
self.main_loss = tf.reduce_mean(
tf.nn.ctc_loss(labels=labels, inputs=chars_logit,
sequence_length=self.seq_inputs_length,
preprocess_collapse_repeated=False,
ctc_merge_repeated=True,
ignore_longer_outputs_than_inputs=True,
time_major=True
))
Then it can run well in all kinds of dataset. but it is too slow, even as slow as standard ctc method, witch 1 step (batch_size=42, label_len is less than 30, GPU 1080TI, CPU I7) need to run 180 seconds !

note that my input placeholder:
tf.placeholder(
shape=(batch_size, height, None, 3),
dtype=tf.float32,
name='image_inputs')

Could anyone help me....
跪求大神，已经折腾很多天了 +_+
note that

[apple55bc]

i know why i can't run warpctc_tensorflow.ctc now !
the width of the input_placeholder must be a constant.
now i solve all the problem.

换setup.py文件，pull request里面有一个支持cuda9的，然后
添加这个到cmakelist.txt里面，重新编译，然后setup装就OK。
