Running with CPU only

[zhao181]

Hello everyone, it is the first time I could successfully run a demo. Many thanks to the author.

To use cpu only, I follow the author's instruction and make the following modifications:
(1) Set "USE_GPU_NMS " in the file ./ctpn/text.yml as "False"
(2) Set the "__C.USE_GPU_NMS" in the file ./lib/fast_rcnn/config.py as "False";
(3) Comment out the line "from lib.utils.gpu_nms import gpu_nms" in the file ./lib/fast_rcnn/nms_wrapper.py;
(4) To rebuild the setup.py:

The author provides the new code of setup.py for cpu only:

from Cython.Build import cythonize
import numpy as np
from distutils.core import setup

try:
numpy_include = np.get_include()
except AttributeError:
numpy_include = np.get_numpy_include()

setup(
ext_modules=cythonize(["bbox.pyx","cython_nms.pyx"],include_dirs=[numpy_include]),
)

(a) execute export CFLAGS=-I/home/zhao181/ProGram1/anaconda2/lib/python2.7/site-packages/numpy/core/include
you should use your own numpy path.

(b) cd xxx/text-detection-ctpn-master/lib/utils
and execute:python setup.py build

(c) copy the .so file from the "build" directory to the
xxx/text-detection-ctpn-master/lib/utils.

(5) cd xxx/text-detection-ctpn-master
and execute: python ./ctpn/demo.py

By the way, I am running under ubuntu 16.04 with
Anaconda2-4.2.0-Linux-x86_64.sh and tensorflow-1.3.0-cp27-cp27mu-manylinux1_x86_64.whl(cpu).

hello, i try to run code on cpu, when i change code according like you, it caused like below:

i have enough 17G RAM and i do not kmow what happened @zhao181 @eragonruan

[zunair11]

Guys , I am trying to run the code on Raspberry Pi 3, I have tensorflow 1.3 installed and have configured the script to use CPU only, but I get the following error when the script demo.py is executed.

I there is any information missing please do ask. Thanks

[zhao181]

I remember that, before I fix the code, there are errors occurring here too. But I forget the details and the solutions. 发自网易邮箱大师 On 12/2/2017 18:09，zunair11<[email protected]> wrote： Guys , I am trying to run the code on Raspberry Pi 3, I have tensorflow 1.3 installed and have configured the script to use CPU only, but I get the following error when the script demo.py is executed.

@zunair11 your device may not have sufficient memory to run the code

[struCoder]

@zhao181
I have follow your steps, but there always with problems:

➜  utils git:(master) ✗ ./make.sh
Traceback (most recent call last):
  File "setup.py", line 39, in <module>
    CUDA = locate_cuda()
  File "setup.py", line 26, in locate_cuda
    raise EnvironmentError('The nvcc binary could not be '
OSError: The nvcc binary could not be located in your $PATH. Either add it to your path, or set $CUDAHOME
mv: rename utils/* to ./*: No such file or directory

And i found the code in lib/utils/setup.py:

CUDA = locate_cuda()

This block code will always exec.

Thanks.

[zhao181]

It seems that you are using a gpu. I run the code only with cpu. I did not run make.sh since I follow the author's instruction and modified the setup.py to compile a cpu support. 发自网易邮箱大师 On 12/4/2017 16:23，David 大伟<[email protected]> wrote： @zhao181 I have follow your steps, but there always with problems: ➜ utils git:(master) ✗ ./make.sh Traceback (most recent call last): File "setup.py", line 39, in<module> CUDA = locate_cuda() File "setup.py", line 26, in locate_cuda raise EnvironmentError('The nvcc binary could not be ' OSError: The nvcc binary could not be located in your $PATH.

@zhao181

Got it.
Thanks a lot.

[zunair11]

@eragonruan I am monitoring the Raspberry Pi resource monitor the ram consumption is shown to be 250 ish MB out of 1 Gigs before the "bad alloc" error is encountered. Do you recommend any work around or is this a dead end for Raspberry Pi's capabilities

[struCoder]

Exec with CPU success, but some difference.
Hope help people in need.

My Sys Env:

• Mac os 10.13.1
• Python3.6.2
• Tensorflow 1.3

For CPU only, here is my setup.py

from Cython.Build import cythonize
import numpy as np
from distutils.core import setup
from distutils.extension import Extension

try:
    numpy_include = np.get_include()
except AttributeError:
    numpy_include = np.get_numpy_include()

ext_modules = [
    Extension(
        'bbox',
        sources=['bbox.c'],
        include_dirs = [numpy_include]
    ),
    Extension(
        'cython_nms',
        sources=['cython_nms.c'],
    )
]
setup(
    ext_modules=ext_modules
)

When execd command python setup.py build, there was new directory build have be created,
and copy build/bbox.cpython-36m-darwin.so and build/cython_nms.cpython-36m-darwin.so file to utils.

[eragonruan]

@zunair11 the code need about 1.5G memory.

[guddulrk]

When I execute CPU only setup.py file, I get following error:
SystemExit: usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands

Can you please help me?

[eragonruan]

@guddulrk python setup.py build_ext --inplace

[guddulrk]

When I run python setup.py build_ext --inplace
it shows me an invalid syntax error.

Any help please

[Guo-king]

When I run pip setup.py build, it appears this error: unable to find vcvarsall.bat.
Should I install the vs for c++ first?

[zhao181]

You should run: python setup.py build_ext --include-dirs={your-numpy-include-path} for example my path is: C:\ProgramData\Anaconda3\Lib\site-packages\numpy\core\include so: python setup.py build_ext --include-dirs=C:\ProgramData\Anaconda3\Lib\site-packages\numpy\core\include and then you will find the .lib files in "./build/temp.win-amd64-3.6/Release" On my PC, the .lib file is "cython_nms.cp36-win_amd64.lib" and "bbox.cp36-win_amd64.lib", you should rename it properly.

[guddulrk]

Thanks, but still I am getting the same error. Any solution, please

[eragonruan]

@guddulrk @Guo-king if your are using windows, use nms and bbox implemented in pure python instead, you have to modify some import

[zhao181]

(1) I use the python command to build the setup.py, like this: python setup.py build_ext --include-dirs=C:\ProgramData\Anaconda3\Lib\site-packages\numpy\core\include I do not know what it will response if pip command is used. (2) you should add your vcvarsall.bat path to the enviroments variables. Generally, if you have visual studio on your machine, the vcvarsall.bat file exists. For many machine, I have vs2013 and vs2015. There all three path for vcvarsall.bat, respectively: You can follow this figure to config your own machine. (3)Still I am not sure which vcvarsall.bat will be used, so if I want to use VS140COMNTOOLS, I will firstly execute the following command: "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat", after switching to the setup.py directory and before building the setup.py, On 12/7/2017 14:48，Guo-king<[email protected]> wrote： When I run pip setup.py build, it appears this error: unable to find vcvarsall.bat.

@zhao181 @eragonruan Thank you for your kindly help. I will try again.

[guddulrk]

When I start running this program I get the following crash on windows 7:
Problem Event Name: BEX64

All other programs in python are running successfully. Anyone who met with this problem. Please help in the solution. Thanks

[newzyh]

I tried a lot of ways. but always got "cannot import name 'bbox'".
come from xxx/lib/utils/init.py
anyone can help?please.
no GPU python3.5

[quanh]

@zhao181 I tried your steps, I got problems of this step:

cd xxx/text-detection-ctpn-master/lib/utils and execute:python setup.py build

Traceback (most recent call last): File "setup_cpu_only_a.py", line 11, in <module> ext_modules=cythonize(["bbox.pyx","cython_nms.pyx"],include_dirs=[numpy_include]), File "/usr/local/lib/python2.7/dist-packages/Cython/Build/Dependencies.py", line 909, in cythonize c_options = CompilationOptions(**options) File "/usr/local/lib/python2.7/dist-packages/Cython/Compiler/Main.py", line 559, in __init__ raise ValueError(message) ValueError: got unknown compilation option, please remove: include_dirs

this is my setup.py:
`from Cython.Build import cythonize
import numpy as np
from distutils.core import setup

try:
numpy_include = np.get_include()
except AttributeError:
numpy_include = np.get_numpy_include()

setup(
ext_modules=cythonize(["bbox.pyx","cython_nms.pyx"],include_dirs=[numpy_include]),
)`

How can i resolve it ? thanks.

I followed @struCoder , resolved it .

[hushenglang]

Dev Environment
Tensorflow-1.3
Python-3.6
cython-0.24

CPU Setting:
(1) Set "USE_GPU_NMS " in the file ./ctpn/text.yml as "False"
(2) Set the "__C.USE_GPU_NMS" in the file ./lib/fast_rcnn/config.py as "False";
(3) Comment out the line "from lib.utils.gpu_nms import gpu_nms" in the file ./lib/fast_rcnn/nms_wrapper.py;
(4) To rebuild the setup.py in path "[path]/text-detection-ctpn/lib/utils/setup.py":
(5) cd xxx/text-detection-ctpn-master/lib/utils
and execute:python setup.py build
(6) copy the .so file from the "build" directory to the
xxx/text-detection-ctpn-master/lib/utils.
(7) cd xxx/text-detection-ctpn-master
and execute: python ./ctpn/demo.py

ps: no need to set env variable "CFLAGS"

you may also need to modify some python file, just follow the error, it is pretty straight-forward

setup.py is like blow:

from Cython.Build import cythonize
import numpy as np
from distutils.core import setup
from distutils.extension import Extension

try:
    numpy_include = np.get_include()
except AttributeError:
    numpy_include = np.get_numpy_include()

ext_modules = [
    Extension(
        'bbox',
        sources=['bbox.c'],
        include_dirs = [numpy_include]
    ),
    Extension(
        'cython_nms',
        sources=['cython_nms.c'],
        include_dirs = [numpy_include]
    )
]
setup(
    ext_modules=ext_modules
)

[daoqinzi]

Thank you for you kindly ways, and i have tried it.

however, when i execute: python ./ctpn/demo.py a problem below occured:

File "/home/aigo/Desktop/text-detection-ctpn-master/lib/utils/init.py", line 6, in
from . import gpu_nms
ImportError: cannot import name 'gpu_nms'

i have solved it by comment "from . import gpu_nms" in file above, maybe you can make your steps more complete.

[struCoder]

@ZhangXinNan
You can try With Python 3.6 version.

[SolinTao]

@honghande lib是lib目录下的文件

[hec44]

does some one got a similar mistake when trying to run "python steup.y build"

[icedlemon]

@hongdajun @xxllp i have the same problem, have you solve it?

[anandi1989]

@honghande Please use in command line/ terminal --
export PYTHONPATH='path/to/text-detection-ctpn/'
then run
python ./ctpn/demo.py
in order to excute the code as project which allow main python file to call other python file inside that folder.
I hope that resolves your issue.

[anandi1989]

@hec44
Are you executing CFLAG command for numpy_include??
I think that is not necessary.

[tianyexing]

run python setup.py build ,but not find .so file
i only find .lib , .exp , .pyd file ?

[JayGou]

follow you guys, but got this err info, would anyone please tell me how to fix it?

I have the same issue with b'Test'. Anyone know how to fix it.

[juanlp]

@JayGou , @SolinTao , the solution can be found at #73

[JayGou]

@juanlp
thx, i run demo.py just by using python2.7, this works for me.

Please can someone tell me what is wrong here

[wangdaqian]

run python setup.py build ,but not find .so file
i only find .lib , .exp , .pyd file ?

I have the same question as yours ,Have you solved this problem?Ask for help,thank you very much!

[tianyexing]

@wangdaqian
you should to see #73. .pyd file can replace .so file

[wangdaqian]

@wangdaqian
you should to see #73. .pyd file can replace .so file

problem solved ，thank you！

[scaler2017]

After following below
#73
I run demo.py on windows with cpu successfully!
my environment is:
windows10 ,
python3.6 ,
tensorflow1.10.0 ,
vs2015(ps: If you do not install Visual C++ please install
Otherwise there is an error : Unable to find vcvarsall.bat )

But there is a problem when I use my train data to run python ./ctpn/demo.py. (change checkpoints_path: checkpoints/ to checkpoints_path: output/ctpn_end2end/voc_2007_trainval in ctpn\text.yml)

The error is as follows：
tensorflow.python.framework.errors_impl.NotFoundError: FindFirstFile failed for: /home/jovyan/work/hd/text-detection-ctpn-master/output/ctpn_end2end/voc_2007_trainval : ϵͳ\udcd5Ҳ\udcbb\udcb
5\udcbdָ\udcb6\udca8\udcb5\udcc4·\udcbe\udcb6\udca1\udca3
; No such process

Is anybody can help me, or teach me how to fix the error? Thank a lot.

@zhao181
I succeeded in getting the result, but the result is a bunch of numbers in the result txt file. How do I display it as a Chinese character?

[ghost]

@zhao181 @eragonruan when running the setup an error message appears:

@hushenglang

(4) To rebuild the setup.py in path "[path]/text-detection-ctpn/lib/utils/setup.py":

What do you mean rebuild the setup.py? How?
because when I run python setup.py build I get the Cuda error you see on top.

Can you upload your the modified setup.py for cpu here?

Hello everyone, it is the first time I could successfully run a demo. Many thanks to the author.

To use cpu only, I follow the author's instruction and make the following modifications:
(1) Set "USE_GPU_NMS " in the file ./ctpn/text.yml as "False"
(2) Set the "__C.USE_GPU_NMS" in the file ./lib/fast_rcnn/config.py as "False";
(3) Comment out the line "from lib.utils.gpu_nms import gpu_nms" in the file ./lib/fast_rcnn/nms_wrapper.py;
(4) To rebuild the setup.py:

The author provides the new code of setup.py for cpu only:

from Cython.Build import cythonize
import numpy as np
from distutils.core import setup

try:
numpy_include = np.get_include()
except AttributeError:
numpy_include = np.get_numpy_include()

setup(

ext_modules=cythonize(["bbox.pyx","cython_nms.pyx"],include_dirs=[numpy_include]),
)
(a) execute export CFLAGS=-I/home/zhao181/ProGram1/anaconda2/lib/python2.7/site-packages/numpy/core/include
you should use your own numpy path.

(b) cd xxx/text-detection-ctpn-master/lib/utils
and execute:python setup.py build

(c) copy the .so file from the "build" directory to the
xxx/text-detection-ctpn-master/lib/utils.

(5) cd xxx/text-detection-ctpn-master
and execute: python ./ctpn/demo.py

By the way, I am running under ubuntu 16.04 with
Anaconda2-4.2.0-Linux-x86_64.sh and tensorflow-1.3.0-cp27-cp27mu-manylinux1_x86_64.whl(cpu).

setup(

ext_modules=cythonize(["bbox.pyx","cython_nms.pyx"],include_dirs=[numpy_include]),
)
is this setup line of code okay as in cythonize function include_dirs is being passed as argument??

[AshleyAnna]

when i run python setup.py build_ext --include-dirs=C:\Users\Administrator\Anaconda3\Lib\site-packages\numpy\core\include,
there is no .so generated and when i try to run demo.py, it will prompt an error that No module named 'lib.utils.bbox'
Is anybody can help me, or teach me how to fix the probelm? Thank a lot.

[wwj-2017-1117]

@ahsannas109 你的setup.py 怎么配置的？ 发出来看看

[NehaMamidwar]

Using CTPN, text from images are detected and results are good. But now hot to recognize or extract text from that boxes. If anybody knows solution for this kindly reply.

[10p-ds-ayesha]

@NehaMamidwar This is text detection library not the text recognition/extraction library.
Use text recognition for your task

[sonuagarwal1008]

Could anybody please tell.
How much time does it take on CPU?

[REBEKAHHHH-ANQI]

Does anyone know how to fix it ?
