Caffe: Cmake could not find url for MSVC version

[mohamadalian]

Hello,
I am a new user of Caffe and I got this error when I wanted to build Caffe on windows:

```

Is there anybody here who can help me?

There are no precompiled dependencies for VS 2013 and Python 3.5. You can:

1. Build the dependencies yourself with caffe-builder
2. Use Visual Studio 2015
3. Use python 2.7

_Please do not post usage, installation, or modeling questions, or other requests for help to Issues._
Use the caffe-users list instead. This helps developers maintain a clear, uncluttered, and efficient view of the state of Caffe.

Cant understand how to : Build the dependencies yourself with caffe-builder
And what is this dependencies , why do I need them . . . why they are not in the git repository why I should care about compiling or building anything I just want to use caffe with python .
I just want to be able to : import caffe !!!!

[Hirosora]

Have you solved your problem?

[stavBodik]

@Haotian9508 Yes I did by using Visual Studio 2015 , the cl.exe which comes with vs 2015 works with python 3.5 in the build step using cmake for windows.
Thanks to @willyd

But this still frustrating because for me all this build things (like in unix based operation systems) was very new...I was sure that I can download project from git with .sln files and just run it...without carrying to compile and build ...

[kathanvyas]

@stavBodik Could you tell me how did you solve the error?
I have visual studio 2015
python 3+

but its giving me the same error

[Hirosora]

@kathanvyas I found this prebuilt binaries, if you just want to use caffe in your project, this may help you.

Visual Studio 2015, CPU only, Python 3.5: Caffe Release
Visual Studio 2015, CUDA 8.0, Python 3.5

[kathanvyas]

@Haotian9508 Thank you so much. But I am fairly new with all this. I downloaded the Visual Studio 2015, CUDA 8.0, Python 3.5 version of caffe. Could you help me out with what steps to follow after this

[Hirosora]

Just copy ~/caffe/python/caffe to ~/python35/Lib/site-packages/caffe and import caffe in your python file.
As for CUDA, I never used it so I don't know how to configure it, maybe you can google for an answer.

[kathanvyas]

@Haotian9508
Thank you so much for helping. I did what you said. I use Anaconda, so pasted caffe in my lib in anaconda. when i try importing caffe, it gives me following error:
" Module use of python35.dll conflicts with this version of Python."
I have python 2.7 as well as python 3.4 working

[Hirosora]

This version of caffe support only python 3.5, you can use anaconda to create a virtual python 3.5 environment. Remember to paste caffe in the venv's lib.

[kathanvyas]

@Haotian9508 Thank you for your help. It now works.

I am getting the same error:
CMake Error at cmake/WindowsDownloadPrebuiltDependencies.cmake:40 (message):
Could not find url for MSVC version = 1913 and Python version = 3.6.

I am completely new in Caffe. I need to use caffe for my masters thesis. It seems very diificult for me to install caffe in windows .So I would really appreciate.Trying for two days to install the caffe........

I am using:
Visual Studio 2017,
Python 3.6.5
Cmake 3.11.1
NO CUDA

[ilyamochalov]

@EhtashamBillah I have the same setup and the same error. Did you solve it?

[gfursin]

@rezaalikhani - if there are no precompiled dependencies, you can try to use CK framework to build Caffe with all sub-dependencies. It was designed to detect your environment and automatically build missing dependencies for your specific compiler and libraries. See related discussion #5631 (https://github.com/BVLC/caffe/issues/5631#issuecomment-351760909) . You can try it as follows:

$ pip install ck
$ ck pull repo --url=https://github.com/dividiti/ck-caffe
$ ck install package:lib-caffe-bvlc-master-cuda-universal --env.CAFFE_BUILD_PYTHON=ON
$ ck run program:caffe

Hope it's of any help ...

[lvZic]

prebuilt binaries is good！

[suleymanov]

@gfursin Hello, can I import caffe in my python scripts if I install it using ck?

[gfursin]

Hi @suleymanov. Yes, you can import caffe in your python scripts after installing it via CK. CK just automates detection of already installed software on different platforms, installation of missing dependencies, and then feeding environment variables to caffe cmake. After that you can use caffe as usual.

After building Caffe via CK, you can test it as follows (if you installed Caffe with python3):

$ ck virtual env --tags=lib,caffe
> python3 
import caffe

CK also creates env.sh with all PATHs, LD_LIBRARY_PATH, PYTHONPATH, etc for any installation via CK. You can see it for caffe as follows:

$ ck cat env --tags=lib,caffe

You can read a bit more about all that here:

@EhtashamBillah @ilyamochalov The problem is solved. You should open cmake\WindowsDownloadPrebuiltDependencies.cmake
and add
set(DEPENDENCIES_URL_1913_27 "${DEPENDENCIES_URL_BASE}/v${DEPENDENCIES_VERSION}/${DEPENDENCIES_NAME_1900_27}${DEPENDENCIES_FILE_EXT}")
set(DEPENDENCIES_SHA_1913_27 "17eecb095bd3b0774a87a38624a77ce35e497cd2")

[dumyCq]

@EhtashamBillah @ilyamochalov Since we have the VS2017 version 1913. You should change the number in C:/Users//.caffe/dependencies/libraries/OpenCVConfig.cmake also.
add
elseif(MSVC_VERSION EQUAL 1913)
set(OpenCV_RUNTIME vc14)
