Issue 1:
I am following this tutorial http://www.bitfusion.io/2016/08/31/training-a-bird-classifier-with-tensorflow-and-tflearn/ I assume that training was done but the system was restarted so I can't verify if the 100 epochs were done. Can you please suggest fixes? Is this a tflearn and tensorflow version mismatch? What can be done?

Issue 2:
Please go to Stack Overflow for help and support:

https://stackoverflow.com/questions/tagged/tensorflow

If you open a GitHub issue, here is our policy:

It must be a bug, a feature request, or a significant problem with documentation (for small docs fixes please send a PR instead).

The form below must be filled out.

It shouldn't be a TensorBoard issue. Those go here.

Here's why we have that policy: TensorFlow developers respond to issues. We want to focus on work that benefits the whole community, e.g., fixing bugs and adding features. Support only helps individuals. GitHub also notifies thousands of people when issues are filed. We want them to see you communicating an interesting problem, rather than being redirected to Stack Overflow.

System information

Have I written custom code (as opposed to using a stock example script provided in TensorFlow):

OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Ubuntu, CPU

Mobile device (e.g. iPhone 8, Pixel 2, Samsung Galaxy) if the issue happens on mobile device:

TensorFlow installed from (source or binary): binary (pip install through anaconda)

TensorFlow version (use command below): 1.8

Python version: 3.6

Bazel version (if compiling from source):

GCC/Compiler version (if compiling from source):

CUDA/cuDNN version:

GPU model and memory:

Exact command to reproduce:

You can collect some of this information using our environment capture script:

You can obtain the TensorFlow version with

python -c "import tensorflow as tf; print(tf.GIT_VERSION, tf.VERSION)"

Describe the problem

Hi, I want to covert a .pb model to .tflite one. The model is train with tensorflow object detection API. The input tensor shape is (None, None, None, 3) but it seems that tflite_convert doesn't support this kind of input.

Source code / logs

ValueError: None is only supported in the 1st dimension. Tensor 'image_tensor:0' has invalid shape '[None, None, None, 3]'.

@pkulzc Do you think this error is caused because we don't provide the input shape for in the ? If so, should we edit this file and set the input shape (dimension of our pictures) ?

Source code / logs

Include any logs or source code that would be helpful to diagnose the problem. If including tracebacks, please include the full traceback. Large logs and files should be attached. Try to provide a reproducible test case that is the bare minimum necessary to generate the problem.
