tensorflowbook's Issues
where is the rest demo code of CNN implementation?
in the chart5 CNN implementation parts, we separate the dogs pictures into training data(80%) and testing data (20%), what is the loss value after 100000times training (if we follow the default setting?), how can we evaluate this CNN module(accuracy and how to use the training model )? who can share the rest demo code or some running result(including the write summary to tensor board graph event)?
lazy_property will cause tensorflow function not to recompute with new batch
The Linear Regression Example is Incorrect.
The code https://github.com/backstopmedia/tensorflowbook/blob/master/chapters/04_
machine_learning_basics/linear_regression.py is not consistent with http://tempforum.neas-seminars.com/Attachment4373.aspx. Also please refer to http://stackoverflow.com/questions/41884411/puzzled-by-linear-regression-results-from-spark-ml-and-tensorflow/41899240#41899240.
Please fix the code, thanks.
Chapter 5 how to use trained model?
The chapter 5 seems truncated, the information about how to use the trained model are completely missing.
chapter 5 working with images page 161
I downloaded the code of ch5's test-input-image.jpg and tried to replicate the results shown at the bottom of the page, array([[[..., but I couldn't get it run.
import tensorflow as tf
import numpy as np
import Image
sess = tf.Session()
image_filename = "test-input-image.jpg"
loaded the image directly in the folder of the script
display images in python
img = Image.open(image_filename)
img.show()
display images in python
print image_filename
filename_queue = tf.train.string_input_producer(tf.train.match_filenames_once(image_filename))
print filename_queue
image_reader = tf.WholeFileReader()
key,image_file = image_reader.read(filename_queue)
print key
print image_file
image = tf.image.decode_jpeg(image_file)
print image
sess.run(tf.global_variables_initializer())
sess.run(image)
print(sess.run(image))
and the results are
<tensorflow.python.ops.data_flow_ops.FIFOQueue object at 0x7f555b882110>
Tensor("ReaderRead:0", shape=(), dtype=string)
Tensor("ReaderRead:1", shape=(), dtype=string)
Tensor("DecodeJpeg:0", shape=(?, ?, ?), dtype=uint8)
Clearly, the image was not read in properly, otherwise why shape=(?,?,?) after decode_jpeg. I also used the python code to display the input at the beginening to make sure the jpeg image was correctly read in, which is true.
I would appreciate it if someone could provide some insights what the problem could be.
Thanks in advance for your time.
Sequence classification: GPU runs out of memory
Maybe the behaviour of dynamic_rnn
changed, or the author used a graphic card with more memory than me, but on a GTX 980 with 4GB, the sequence classification code doesn't run.
I think the reason is that the length of the longest review is around 2700, and 2700x300xbatch_size
is too much for the card. It would be nice if the book addressed this issue.
I guess a solution would be to unroll the network to e.g. 50 steps, but still feed the batches... is it possible?

The iterative batch generation code is so strange to me in Chapter 6 04_arxiv preprocessing.py.
First, for i in range(0, len(text) - self.length + 1, self.max_length // 2):
. I'm sorry, but what if len(text) is actually smaller than self.length(I assume it's the max_length)? And Why would I need to do this process?
Second, assert all(len(x) == len(windows[0]) for x in windows)
. Why do I need to make every text the same length?
Next, the following while True
. Isn't it going to loop infinitely?
Last, batch = windows[i: i + self.batch_size]
. I don't think last batch generated will be the same size as previous ones in first dimension.
Hope someone could answer my questions:)
the first dimension of the kernel variable
I don't understand the following sentence in 05_object_recognition_and_classification:
In the example code, there is a single kernel which is the first dimension of the kernel variable.
Acorrding to the document the shape of kernel is [filter_height, filter_width, in_channels, out_channels]
, the first dimension of the kernel is filter_height
.
I found it is rather slow when converting images to TFRecords, is it normal?
This is my computing environment: Ubuntu 16.04+gtx1080+cuda8.0rc+python2+Tensorflow 0.10.0. I realized that your codes are Python3.x suited, but that's not a problem. The real problem is when I was testing write_records_file
function in Chapter 5 - 05 CNN Implementation.ipynb, at first the process was well running, quite okay... but after a while, it took almost 20s to 30s to generate one TFRecord object! I checked the usage of my graphic card, only 2% memory was being used. Then I switch to CPU only mode, I opened all the 28 threads to run the code, but nothing got better, it was still pretty slow, the usage of CPU was 5% to 8%...Is it normal?
Chapter 6 04_arxiv not suitable for tensorflow2.x version?
Could not load dynamic library 'libcudart.so.10.1'; dlerror: libcudart.so.10.1: cannot open shared object file: No such file or directory; LD_LIBRARY_PATH:
rnn_cell = tf.nn.rnn_cell.GRUCell
AttributeError: module 'tensorflow._api.v2.nn' has no attribute 'rnn_cell'
It seems that the code is not suitable for tensorflow2.x version
ch5 - pg 179 suggestion
Hey, Really enjoying the book!
A few pages earlier you suggested adding a folder for the exporting of the dog data set.
Right before you start the def write_records_file(...)
, it seems it would be useful to mention adding the output/training-images and output/testing-images to your directories to avoid the error of running the ipynb for this section (CCN Implementation).
Thanks!
the accuracy of chapter5
Can you show the accuracy of chapter5 on test dataset.
I training the model and the accuracy is quite low.
H Image - Chapter 5, Page 175
I have copied the H image on page 175 to my computer (right click, "Save Image As") but when I run the code, Python just runs forever, and I can't interrupt it. I have the latest version of TensorFlow. Am I doing something wrong?
import tensorflow as tf
image_filename = "my_dir/H.jpg" # Location of the H image on my computer.
filename_queue = tf.train.string_input_producer([image_filename])
image_reader = tf.WholeFileReader()
_, image_file = image_reader.read(filename_queue)
image = tf.image.decode_jpeg(image_file)
sess = tf.Session()
sess.run(image)
Ch. 6. Word Vector Embeddings - Python 2.7
Hi Guys,
I've been using the book in the last days and now I arrived at Ch 6. I am struggling to make the code from the section Word Vector Embeddings work using python 2.7.
Until now I have changed a few things, i.e.
- All the
bz2.open()
occurrences replaced withbz2.BZ2File()
from urllib.request import urlopen
replaced withfrom urllib import urlopen
Now I am stuck with the _read_pages(self, url)
method... This is the error that get.

Typo on Chapter 3
There is a small Typo in Chapter 3
1-D Tensor with boolean data type
t_2 = np.array([[True, False, False], [False, False, True], [False, True, False]], dtype=np.bool)
This should have said 2-D Tensor and not 1-D.
The memory of the TensorFlow node object could not be reclaimed
When I try to ran the code Chapter 5 - 05 CNN Implementation.ipynb
. I noticed that the memory of the TensorFlow node object could not be reclaimed(For example image_file = tf.read_file(image_filename)), and as the for loop in the write_records_file method deepened, the python program took more and more memory, causing me to fail to write all the converted Picture file. What is your solution to this problem?
CNN Implementation
Would it be possible to have some code to run and evaluate the CNN Implementation model?
Thanks!

Chapter 6?
Is any code available from chapter 6 particularly the Char RNN?
Ch 4 Logistic regression file address
This mechanism to create full path:
filename_queue = tf.train.string_input_producer([os.path.dirname(__file__) + "/" + file_name])
produces just '/train.csv' for me on Mac OSX.
That generates a confusing and scary stack trace, which misleads a Tensorflow novice for quite some time.
Finally when I removed the path setting, the code works just fine (naturally requires that input file is in the same folder):
filename_queue = tf.train.string_input_producer([file_name])
