MacOS 10.12.6

TensorFlow installed from (source or binary):

anaconda3

TensorFlow version (use command below):

v1.7.1-0-gc8137f3a8e 1.7.1, as TOCO wouldn't work on 1.8

Python version:

Python 3.6.5 :: Anaconda, Inc.

Bazel version (if compiling from source):

N/A

GCC/Compiler version (if compiling from source):

N/A

N/A

Describe the problem

When trying to build the "tflite" app from tensorflow-for-poets2, I encounter an error; Multiple dex files define Lorg/tensorflow/lite/NativeInterpreterWrapper;. I have tried updating the SDK and finding a duplicate of the file defining NativeInterpreterWrapper (with no luck).

Environment info

Operating System: Ubuntu 16.04.1 LTS

Installed version of CUDA and cuDNN: none

pip package: https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.10.0-cp27-none-linux_x86_64.whl

$ python -c "import tensorflow; print(tensorflow.version)"

0.10.0

If possible, provide a minimal reproducible example (We usually don't have time to read hundreds of lines of your code)

Using commands from https://www.tensorflow.org/versions/r0.9/get_started/index.html to create a model:

import tensorflow as tf
import numpy as np
x_data = np.random.rand(100).astype(np.float32)
y_data = x_data * 0.1 + 0.3
W = tf.Variable(tf.random_uniform([1], -1.0, 1.0))
b = tf.Variable(tf.zeros([1]))
y = W * x_data + b
loss = tf.reduce_mean(tf.square(y - y_data))
optimizer = tf.train.GradientDescentOptimizer(0.5)
train = optimizer.minimize(loss)
init = tf.initialize_all_variables()
sess = tf.Session()
sess.run(init)
sess.run(train)

Then this works:

saver = tf.train.Saver()
saver.save(sess, 'my-model')
sess = tf.Session()
new_saver = tf.train.import_meta_graph('my-model.meta')

But this doesn't:

tf.train.export_meta_graph(filename='my-model.meta')
new_saver = tf.train.import_meta_graph('my-model.meta')

Traceback (most recent call last):

File "", line 1, in

ValueError: At least two variables have the same name: Variable_1

What I actually want to use is this, which also does not work (same error):

meta_graph_def = tf.train.export_meta_graph()
saver = tf.train.import_meta_graph(meta_graph_def)

I need a solution that does not rely on the file system.

Am I doing something wrong?

What other attempted solutions have you tried?

I tried to look at the files to see where these duplicated names occur but did not find any.
