python setup.py install error

python setup.py install error in cudarray setup command: CUDA back-end wants to be able to remove cudarray.cudarray_wrap, but the distribution doesn't contain any packages or modules under cudarray.cudarray_wrap

How to solve, thank you very much

I update the setup.py. Now another problem is ： “”running build_ext building 'cudarray.numpy_backend.nnet.conv_bc01' extension gcc -std=gnu99 -fno-strict-aliasing -g -O2 -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -fPIC -I/usr/local/lib/python2.7/site-packages/numpy/core/include -I/usr/local/include/python2.7 -c cudarray/numpy_backend/nnet/conv_bc01.c -o build/temp.linux-x86_64-2.7/cudarray/numpy_backend/nnet/conv_bc01.o gcc: cudarray/numpy_backend/nnet/conv_bc01.c: No such file or directory “” I am not familiar with cpython and I indeed could not find cudarray/numpy_backend/nnet/conv_bc01.c. Is the conv_bc01.c generated by compling the code at the first step "make"?

The version of cython is 0.22 Python version: 2.7

[andersbll]

conv_bc01.c gets generated by the call to cythonize().

Regarding your initial problem: You might need to call sudo python setup.py install because you are trying to install to system directories. Alternatively, you could perform a user install.

Thanks for your quick reply, I will try your method. If I want to code my own c++ cuda function for some special cases, how can I embed the c++ cuda function into python routine, Need I to learn cython first? could u give quick guide?

thank you

[andersbll]

You need to 1) implement your CUDA functionality, 2) wrap the functionality in Cython and 3) expose it to Python using cudarray.ndarray objects.

Hi andersbll sorry to bother you again, I try to install it today again, but another problem is " Traceback (most recent call last): File "setup.py", line 5, in import numpy File "/usr/local/lib/python2.7/site-packages/numpy/init.py", line 153, in from . import add_newdocs File "/usr/local/lib/python2.7/site-packages/numpy/add_newdocs.py", line 13, in from numpy.lib import add_newdoc File "/usr/local/lib/python2.7/site-packages/numpy/lib/init.py", line 18, in from .polynomial import * File "/usr/local/lib/python2.7/site-packages/numpy/lib/polynomial.py", line 19, in from numpy.linalg import eigvals, lstsq, inv File "/usr/local/lib/python2.7/site-packages/numpy/linalg/init.py", line 50, in from .linalg import * File "/usr/local/lib/python2.7/site-packages/numpy/linalg/linalg.py", line 29, in from numpy.linalg import lapack_lite, _umath_linalg ImportError: libmkl_rt.so: cannot open shared object file: No such file or directory " PS: The numpy(1.8) used on my machine was complied with MKL and it worked. I also set the enviroment var path for MKL LIB.

Sorry, can't help you with that.

OK, thank you all the same. By the way, does cudarray support selection as follows：" row_select_index=[0,2,3,10,0],gp_A is a garray with a shape(M,N) gp_A[row_select_index] ？
