below is the running log. i added some printf in the program.
and locate the error happens at line 60 in the file clstm_compute.h
the code calls the sum function of a tensor1 variable.
the version of Eigen i use is Eigen3.3-beta1
need some help here, thank you

Hi @tmbdev,
I am trying to figure out how the CTC works in clstm and got stuck.
I'm confused when looking into the following code in ctc.cc
.
void forward_algorithm(Mat &lr, Mat &lmatch, double skip) {
int n = ROWS(lmatch), m = COLS(lmatch);
lr.resize(n, m);
Vec v(m), w(m);
for (int j = 0; j < m; j++) v(j) = skip * j;
for (int i = 0; i < n; i++) {
w.segment(1, m-1) = v.segment(0, m-1);
w(0) = skip * i;
for (int j = 0; j < m; j++) {
Float same = log_mul(v(j), lmatch(i, j));
Float next = log_mul(w(j), lmatch(i, j));
v(j) = log_add(same, next);
}
lr.row(i) = v;
}
}
I'm wondering what the argument skip
means since it not in the original thesis of Graves nor in the source code of rnnlib.
Thanks!
I meet a problem when I am trying to compile this code. I use scons in command. But it shows this error.

Can anyone give me a help? Thanks
Could you be kind enough to provide trained models like you do for ocropy/ocropus?
To enable resumed ocrtrain, I am trying to load *.clstm. but when I reload, parse error occurs with this message.
[libprotobuf ERROR google/protobuf/message_lite.cc:123] Can't parse message of type "clstm.NetworkProto" because it is missing required fields: kind, ninput, noutput
libc++abi.dylib: terminating
These 3 fields(kind, ninput, noutput) are not saved?
I used be able to run setup.py fine, in the latest two version i get swig errors (setting the NPY version doesn't fix it).

Hi @tmbdev , I did some experiments about offline handwriting recognition with clstm. The network can produce one sequential result by given image.
Is it possible to get confidence values of the result? For example, as shown in the image given by #18 , every position of the sequence has different colors for different predictions.
Are there any interfaces in clstm to get such confidence values?
Thanks.

looking forwards to the MDLSTM version
I have seen that in the last version genericLSTM has been "softly" deprecated. Could you please explain me the reason why this choice has been made?
would be good to have one. the files generated seem to be only for seq.
it would be very nice to provide a code or a high level description of using 2DLSTMs in CLSTM for OCR tasks.
going though the image filter example in test-2d.cc with 1x1 patch (if I understand right) it is not that obvious how to use 2DLSTMs in e.g. clstmocrtrain.cc
direct replacing of BLSTM with 2DLSTM would compile and work but won't converge and would be using 48x1 (i.e. 1D) patches.
What one would like to try is using instead e.g. 1x2 or 2x4 as in here or here
Also, I would like to ask what are the limitations of CLSTM implementation compared to RNNLIBs' when handling 2DLSTMs
Thanks,

I tried to compile and "setup.py build" with clstm, when I did
python
import clstm
I got "_clstm.so: undefined symbol: _ZN7ocropus14default_deviceE" The platform is Ubuntu 14.04. I am using Anaconda python.
Given the name, I suspect the symbol is related to ocropy, so I tried to install the python packaged of ocropy. But I still get the same error. Would anyone mind to give me some hints? Thanks in advance for your time. And sorry if this is a trivial issue.

For many models (especially deep ones with many parameters e.g. bidi2), I keep getting the following error
clstm.cc:664: void ocropus::GenericNPLSTM<F, G, H>::backward() [with int F = 1; int G = 2; int H = 2]: Assertion `!anynan(out)' failed.
where the old version (Mat-based) works just fine
when I try to use command like this to compile
scons -j 4 gpu=1 clstmocrtrain clstmocr
but failed to enable GPU, what is the right things to do to use GPU to speed up the training process?
I am using a pretrained clstm language model and loading it.
This is my code:
def PredictWords(self,image):
noutput = 3877
if self.lang == "EN":
pass
elif self.lang == "JP":
net = clstm.load_net("../lang/jp3877.clstm")
net.inputs.aset(image)
net.forward()
prod = net.outputs.array()
seq = clstm.Sequence()
seq.aset(target.reshape(-1,noutput,1))
aligned = clstm.Sequence()
aligned = aligned.array()
return clstm.Codec.decode(prod)
But this error occurs:
[libprotobuf ERROR google/protobuf/message_lite.cc:123] Can't parse message of type "clstm.NetworkProto" because it is missing required fields: kind, ninput, noutput
I think I am mistaking loading the neural net model or need more specific parameters to load it. How to solve this problem?
@tmbdev I have a question about is this clstm suitable for Scene Text Recongnition. I extract feature sequence from raw images(use CNN), Now, I want use the CNN feature sequence to train the blstm+ctcRNN,but I don't know how to create the .h5 file for training(use the CNN feature sequence). Can you provide an example?
With 500-character subset of Japanese Kanji, clstm works fine. (hidden_nodes = 100, MacBook, gcc48 from homebrew)
Your kid reads Japanese brilliantly.
I am trying 2492-char subset. it seems to take several weeks (hidden=200, this time)
(NO nhidden = 200 seems to be hopeless, he/she seems to learn one char by forgetting another)
Now trying 3700 chars( little bigger tesseract jp-dataset ) with nhidden = 800 and nhidden =1200.
Unless my PC broke, I will see the result next spring.
I tried to import clstm python module but this following error happens:

25 return _clstm
26 if fp is not None:

How can I solve this error? I did scons

command and I saw the README that python setup.py build
command is broken.
Hi,
I was working on a GUI for scanning PDF documents and I was looking
for a way to have correct OCR under Linux and to sandwich the text into the generated PDFs.
Obviously the state of open source OCR isn't stellar, everything I tried wasn't exactly a breeze
to setup and most importantly the actual detection was quite bad for example with tesselact and
all the other known open source projects.
Then I read about ocropy/ocropus/clstm, and finally was relieved that someone was at last working from scratch on an innovative modern approach, that was actually being actively developed and some of the results I saw in one online tutorial where a guy modified the model for typewriter fonts and it worked rather good were promising.
So I got ocropy to work on Fedora and tried it with the standard model on a simple plain PDF document I had scanned. The results were just as terrible as with the other open source OCRs, if not worse, although it really is a high resolution scan with normal looking fonts. I felt disappointed to be honest.
From the documentation/README.md and so on I didn't get a lot of information about where the project is going and where it might need some help. The basic concepts are explained well, but I didn't get a good picture of where the problems of the project are and what is done to solve them.
It seems "the model" is just a file that was uploaded sometime ago, but doesn't get actively maintained and improved currently.
I would be interesting to know what the obstacles currently are for supporting more fonts/fontstyles and so on. Is there any plan for what the next milestones should be? Is there any guide how people can best help the project to fix bugs, add features, refactor code, improve models and so on.
I'm writing this in this project, because I really see it as the same project basically.
To summarize:
I'm sorry, if this doesn't fit into "issues". Feel free to remove or move this, I just
wanted to express that what's going on with ocropy/clstm development seems
like a blackbox from the outside.
Hello, have anyone tried clstm to handwriting recognition? I have just applied it for the IAM dataset(http://www.fki.inf.unibe.ch/databases/iam-handwriting-database), but there isn't a good performance(33.5% error ratio after 200,000 iterations). I used the config like run-uw3-500, and tried to modify the parameters(e.g. set hidden to 500, 300, set lrate to 1e-4, 1e-3), but the performances are almost the same. Can anyone give me some suggestions? Many thanks~
Thanks,
I am a beginner in LSTM.My doubt is, with what I have understood LSTM wont do just OCR rather it will also try to predict the next word or character unlike tesseract.But suppose I am training for say a set of pronouns like names,places etc should I train for all possible names and places.Because given a new place with say 2 words, clstm may try to predict the next word and if that is not in the training set,will it do OCR alone rather than predicting it? bcz prediction may be completely wrong if it is not in the dataset?
I tried for person names and I trained over the english default model when I give different name other than in the dataset,it is failing very badly.Any thoughts will be helpful
I suffered a lot to come to code clstm python with the original dataset using opencv2 and python. Hope this code helps other people trying to use clstm python.

There are some things the currently trained models for ocropus-rpred will not handle well, largely because they are nearly absent in the current training data. That includes all-caps text, some special symbols (including "?"), typewriter fonts, and subscripts/superscripts. This will be addressed in a future release,
clstm_wrap.cpp:6375:15: error: no member named 'resize' in 'ocropus::Batch'

~~~~~~ ^
clstm_wrap.cpp:6426:15: error: no member named 'setZero' in 'ocropus::Batch'

The current wstring is not entirely portable, since wchar_t is only 16 bits on Windows. Occurrences of wchar_t should be replaced with char32_t and occurrences of wstring with u32string
'ntrain' appears in these files:
'maxtrain' appears in these files:
Tom, please use either 'ntrain' or 'maxtrain' for the parameter name in all files.
Any documentations/tutorials to train models and to test for OCR?
@tmbdev I have a question about is this clstm suitable for offline English handwriting. I am newer to this area. I have some questions for discussion.
It seems that clstm network will mapping this character to label. So it's better to do some norm operation of this handwriting words? So it has better segmentation result for easy recognition.
What Gradient Descent Method clstm is using? SGD? AdaGrad? NAG? RMSProp? Adam?
I want to increase the speed of the learning.
If clstm is not using adaptive learning rate algorithm, I also have to ask that this method can change the learning rate dynamically to implement adaptive learning rate algorithm:
net.setLearningRate(1e-4,0.9)
In the previous version, one can accelerate calculation using "usemat=1" during installation, which use matrix instead of tensor. But in the current version, the matrix alternative is not supported. Is this means the tensor version is as fast now? Why matrix part is removed?
Best
Is there any way to give a gold-standard alignment to CLSTMText?
I'm working on some research evaluating its efficacy on other tasks besides OCR, such as Twitter, where expanding acronyms is a big deal. Right now clstmtext is suffering mightily because it takes text lines directly instead of letting me give it the direct alignments (e.g. two sequences, ["lol", "wut"] --> ["laughing out loud", "what"])
Anything I can do to help it on this front?
Hi @tmbdev , thanks for your reply in #24, it is perfect!
I have another question and have commented in #24.
Here I copy the question for easier retrieval for other people.
Can the predict interface provide top-N results?
That will be helpful for better results and finding weakness of datasets.
Thanks.
hello,I loaded your code,it's very amazing! I know little about it so i have some questions.
when i run ./test-lstm , it gives error: test-lstm.cc:80:3: error: use of undeclared identifier 'unlink'; did you mean 'inline'?After googled, I add head file #include <unistd.h> and solve this problem.
Then run ./test-filter.sh , it gives anther error :./test-filter.sh: line 7: 26632 Illegal instruction: 4 hidden=20 ntrain=1001 neps=0 report_every=200 save_every=1000 lrate=1e-2 save_name=_filter ./clstmfiltertrain _filter.txt
clstmfilter FAILED
how can I do with it ?
Using RHEL 6.5
I've installed hdf5 and hdf5-devel
I've looked in the SConstruct and gave the hdf5lib=hdf5_serial option.
I even added some debug code to make sure it was accepting it.
No matter what I do, the code moves forward without error and installs the regular tools, but none of the HDF5 tools.
Any ideas?
At 171-173 in clstmocrtrain.cc, errors and count seems to be turned over.
double errors = tse.first;
double count = tse.second;
Or, test_set_error should return an inverted pair.
I'm trying to use the C++ version CLSTM in ocropy . i tried building the python parts using setup.py but it throws errors
