Error when importing blocksparse: `undefined symbol: _Z11GetCountSMsv`

[linzwatt]

I am having trouble importing your blocksparse library after compiling and pip-installing the built package. I am compiling using cuda 10 and the latest tf built from source, so I imagine this could be the issue as you mention using cuda 8 and tf 1.4.0. I'd like to try and get it working with the latest tf, as the rest of our pipelines and models are built upon the latest version

I found several references to GetCountSMs() and GetCountSMsVersion() in the source code, but could not find anything called _Z11GetCountSMsv

Thanks in advance for any help
