Error in using glue_stick_demo.ipynb

[shenw000]

When I run the command "import homography_est as hest" in glue_stick_demo.ipynb, the following error appears:

---

ImportError Traceback (most recent call last) Cell In[1], line 1 ----> 1 import homography_est as hest 3 line_seg0 = [hest.LineSegment(l[0], l[1]) 4 for l in matched_lines0.reshape(-1, 2, 2)] 5 line_seg1 = [hest.LineSegment(l[0], l[1]) 6 for l in matched_lines1.reshape(-1, 2, 2)]

ImportError: /lib/libceres.so.1: undefined symbol: _ZN6google21kLogSiteUninitializedE

---

So I look into the version of /lib/libceres.so.1, by command: ls -ll /lib/* | grep libceres the following appears:

---

-rw-r--r-- 1 root root 9847228 Jun 12 2020 /lib/libceres.a lrwxrwxrwx 1 root root 13 Jun 12 2020 /lib/libceres.so -> libceres.so.1 lrwxrwxrwx 1 root root 18 Jun 12 2020 /lib/libceres.so.1 -> libceres.so.1.14.0 -rw-r--r-- 1 root root 2824976 Jun 12 2020 /lib/libceres.so.1.14.0

---

That means the actual version of /lib/libceres.so.1 is /lib/libceres.so.1.14.0 Is this the correct version for /lib/libceres.so.1? Any suggestion how to fix it?

Hi,

It looks like you have a different version of ceres and there is some missing symbol. I think the missing symbol comes from glog.

Can you compare the versions of ceres and glob that you have with the ones in Google Colab?

Best, Iago.

Thank you for the info, lago-suarez! How do I find the version number of libceres and glog used in Google Colab. My versions for libceres and glog are:

ls -ll /lib/* | grep libceres -rw-r--r-- 1 root root 9847228 Jun 12 2020 /lib/libceres.a lrwxrwxrwx 1 root root 13 Jun 12 2020 /lib/libceres.so -> libceres.so.1 lrwxrwxrwx 1 root root 18 Jun 12 2020 /lib/libceres.so.1 -> libceres.so.1.14.0 -rw-r--r-- 1 root root 2824976 Jun 12 2020 /lib/libceres.so.1.14.0

ls -ll /lib/* | grep glog -rw-r--r-- 1 root root 261226 Mar 22 2020 libglog.a lrwxrwxrwx 1 root root 16 Mar 22 2020 libglog.so -> libglog.so.0.0.0 lrwxrwxrwx 1 root root 16 Mar 22 2020 libglog.so.0 -> libglog.so.0.0.0 -rw-r--r-- 1 root root 138440 Mar 22 2020 libglog.so.0.0.0

Hi, sorry for late reply, it has been a busy week. You can run the same commands in Collab, you just need to add ! In the beginning.

Cheers, Iago.
