problems with python and somoclu on osx - no training, missing a linked library?
jazoza opened this issue · comments
Hello,
I wanted to test the but have not been able to get it running. I have two machines: a 13'' MacBook (osx 10.13.4 no GPU) and a Mac Pro desktop (osx 10.10.5) with an NVIDIA GeForce GTX 650 Ti and CUDA Driver Version: 7.5.27. Laptop is running python 3, desktop 2.7, both through anaconda.
when installing somoclu with the standard command
conda install somoclu
I get this error when importing to python:
>>>import somoclu
RuntimeError: module compiled against API version 0xc but this version of numpy is 0xa
Warning: the binary library cannot be imported. You cannot train maps, but you can load and analyze ones that you have already saved.
If you installed Somoclu with pip on macOS, this typically means missing a linked library. If you compiled Somoclu with GCC, please make sure you have set DYLD_LIBRARY_PATH to include the GCC path. For more information, please refer to the documentation.```
When I install somoclu using the latest code from the git repository, as suggested in the documentation, the error is simply that there is a missing library and that I cannot train.
`>>> import somoclu`
```Warning: the binary library cannot be imported. You cannot train maps, but you can load and analyze ones that you have already saved.

This is the same on both machines.
On the desktop, I have installed CUDA drivers and toolkit,
`$ /usr/local/cuda/bin/nvcc --version` gives the following output:
```nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2015 NVIDIA Corporation
Built on Mon_Apr_11_13:23:40_CDT_2016
Cuda compilation tools, release 7.5, V7.5.26```
`$ gcc --version` is the following:
```Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.1.0 (clang-602.0.49) (based on LLVM 3.6.0svn)
Target: x86_64-apple-darwin14.5.0
Thread model: posix```
I have set the CUDAHOME variable and the python install script is able to detect it.
During the `sudo python setup.py install` build, the nvcc command fails with the error:
`nvcc fatal : The version ('60000') of the host compiler ('clang') is not supported`
Which, as far as I understand is caused by the incompatibility of my cuda and my clang versions. I downgraded xcode and clang from 7 to 6, but the issue persists.
The install however, completes, and the result is the same: no training, missing library.
`>>> import somoclu`
```Warning: the binary library cannot be imported. You cannot train maps, but you can load and analyze ones that you have already saved.
If you installed Somoclu with pip on macOS, this typically means missing a linked library. If you compiled Somoclu with GCC, please make sure you have set DYLD_LIBRARY_PATH to include the GCC path. For more information, please refer to the documentation```
Could you please tell me where in the documentation I can find more about which library to look for and whether this error is cause by a dependency conflict on (both of) my machines or is it rather a matter of OSX? How could I get somoclu to run on either on these?
Thank you!

We discussed macOS-related problems and the current solution in gory details in this issue. The only thing we can do is to ensure that it passes the OSX build with Travis CI with conda (see the corresponding recipe.
Maybe you should try install the same version of numpy that conda forge uses.
