E: Version '1:4.4.6-1' for 'libsuitesparse-dev' was not found

Could you tell me if you added some repository before install it, I cannot find a solution to install libspqr2.0.2 from google. And my libspqr in /usr/lib/x86_64-linux-gnu is libspqr2.0.8.

from pvnet.

I am still not able to use it on ubuntu 18.04 because of this error. So it is better to let this issue stay open.

I solved the problem by re-compiling the Ceres and got new libCeres.so, in this case, you do not need to rely on the specific libspqr.2.0.2.

from pvnet.

The PVNet depends on the Ceres Solver for the solving uncertainty PnP problem.
You can follow the installation tutorial in http://ceres-solver.org/installation.html.

The following steps are essential for building a shared ceres library.

# - However, if you want to build Ceres as a *shared* library, you must
#   add the following PPA:
sudo add-apt-repository ppa:bzindovic/suitesparse-bugfix-1319687
sudo apt-get update
sudo apt-get install libsuitesparse-dev

from pvnet.

Reading README.md is a good habbit, and you will feel it.

I found my libspqr in /usr/lib/x86_64-linux-gnu/ is 2.0.8.
so I met error when running data_utils.py as follow:
Traceback (most recent call last):
File "lib/utils/data_utils.py", line 18, in
from lib.utils.extend_utils.extend_utils import farthest_point_sampling
File "/home/jiaming/pvnet/lib/utils/extend_utils/extend_utils.py", line 3, in
from lib.utils.extend_utils._extend_utils import lib, ffi
ImportError: libspqr.so.2.0.2: cannot open shared object file: No such file or directory
Could this be solved?

Do you have solved this error? i have the same error,

from pvnet.

sudo apt-get install libsuitesparse-dev

from pvnet.

install libsuitesparse-dev cannot solve this problem, though I tried from the very beginning for several times.
I'm still trying to figure out.

Please run the following command and paste its output
cd /usr/lib/x86_64-linux-gnu; ls | grep libspqr

from pvnet.

cd /usr/lib/x86_64-linux-gnu

its output:
libspqr.a
libspqr.so
libspqr.so.1.3.1
but i how to install libspqr.2.0.2?

from pvnet.

sudo apt-get install libsuitesparse-dev=1:4.4.6-1 might help.

I have updated README.md. Thanks for your correction.

from pvnet.

I found this problem may caused by my usage of ubuntu 18.04, which do not support libsuitesparse-dev 1:4.4.6-1 or any of its depends libs.
I will try with another system and tell you the result.
Thanks for help.

Could you tell me how to re-compile Ceres or just upload the libCeres.so

from pvnet.

Ok, thank you! I get it.

I write a script to build ceres: https://github.com/zju3dv/pvnet/blob/master/build_ceres.sh
