Have you compiled sucessfully?

[lijunling]

yes,when I run demo.py ,it throws the error.

[dmxj]

you can try re-pull the code and build it again

[arcral]

I built the latest code, and also met question like this.
ImportError: /root/.local/lib/python3.6/site-packages/cpools-0.0.0-py3.6-linux-x86_64.egg/top_pool.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZTIN3c1021AutogradMetaInterfaceE

I have same problem when run demo.py.

I change the pytorch to 0.4.1 because my cuda is 9.0.

How to solve it? Thanks

[andyhahaha]

I have the same error.
gcc 5.4.0

[feiyuhuahuo]

If comes with this error:undefined symbol: _ZN3c105ErrorC1ENS_14SourceLocationERKSs, follow 'Getting started' to create a new environment. Try not to run in your old environment, because it's easy to meet environment incompatible problem. I ran the demo firstly in my own environment and it appears error. Then I create a new environment and do as the 'Getting started' told, it works succesfully.

怎么解决，我以前是重新编译了一下，但是现在好像重新编译也不行了

[LewX]

How to solve it?

[caikw0602]

Yes, the same problem.

[njustymk]

the same problem. How to solve it?

[syedibnmohsin]

I have the same problem, I am running it on VirtualBox. Is it because the VM doesn't have access to the host GPU?
