I have libcaffe-nv.a  libcaffe-nv.so  libcaffe-nv.so.0  libcaffe-nv.so.0.11.0 in my caffe/build/lib
thanks!

I would expect you to have a symlink at libcaffe-nv.so.0.11 as well.

$ ls -l build/lib/
total 6932
lrwxrwxrwx 1 lyeager git-user      14 Oct  2 09:50 _caffe.so -> _caffe.so.0.13
lrwxrwxrwx 1 lyeager git-user      16 Oct  2 09:50 _caffe.so.0.13 -> _caffe.so.0.13.2
-rwxr-xr-x 1 lyeager git-user 1273673 Oct  2 09:50 _caffe.so.0.13.2
lrwxrwxrwx 1 lyeager git-user      19 Oct  2 09:49 libcaffe-nv.so -> libcaffe-nv.so.0.13
lrwxrwxrwx 1 lyeager git-user      21 Oct  2 09:49 libcaffe-nv.so.0.13 -> libcaffe-nv.so.0.13.2
-rwxr-xr-x 1 lyeager git-user 4792476 Oct  2 09:49 libcaffe-nv.so.0.13.2
-rw-r--r-- 1 lyeager git-user 1024940 Oct  2 09:48 libproto.a

If you inspect the library, you should see that the SONAME is libcaffe-nv.0.11:

$ readelf -a build/lib/libcaffe-nv.so | grep SONAME
 0x000000000000000e (SONAME)             Library soname: [libcaffe-nv.so.0.13]

Hello Luke! Thanks for answering :)
0x000000000000000e (SONAME)             Library soname: [libcaffe-nv.so.0]

It's my result!
but how can I upgrade it to libcaffe-nv.so.0.13?
Thanks

Oh... looks like we've got a bug in the Makefile versioning. That's supposed to be libcaffe-nv-so.0.11.

I've fixed it in the v0.13 branch with this pull request - I suggest you upgrade to v0.13 if you want to continue using Make. I usually use CMake, personally.

Oddly, DIGITS is still working for me when I build v0.11.0 with Make, like you did.

What version of DIGITS do you have? Check digits/__init__.py.

finally I can execute DIGITS with the right version!
but I got the other problem like this:

 ___ ___ ___ ___ _____ ___

 | |) | | (_ || |  | | \__ \
 |___/___\___|___| |_| |___/

Something went wrong when loading libcudart.so

You don't have datetime? That's weird. Is python installed on your system? What OS are you using?

FYI, you can always just install datetime with pip install datetime.

My DIGITS version is DIGITS-1.1

You'll probably be happier if you update DIGITS as well. v2.0 should be very stable. Or you can be a little more adventurous and get v2.2.
