I am using python 3.6 on Ubuntu 16.04. I have just updated pytorch via conda. But, I got an following error when torch was imported.

this makes no sense yet, because python 3.6 should be having that. Let’s try to figure this out. Can you please paste your output of the following command: ```auto ldd /home/sypark/anaconda3/lib/python3.6/site-packages/torch/_C.cpython-36m-x86_64-linux-gnu.so ``` ---

I do not the reason, I got the out of memory error. Compared to the latest, the previous version consumes 9GB only (12GB total). I should stay at the previous version for a while. Thanks. ---

what is your application? is your code available somewhere to look? ---

ok the problem is pytorch version `0.1.11_4`. It had this problem and I updated it to `0.1.11_5` which did not have this issue. Can you do: ```auto conda uninstall pytorch conda install pytorch -c soumith ``` Verify that it is installing `0.1.11_5` ---
