Hello , still the same! echo $PATH and sudo echo $PATH gives -> /usr/local/cuda/bin:/usr/local/bin:/usr/bin:/bin:/opt/bin:/usr/x86_64-pc-linux-gnu/gcc-bin/4.6.2:/usr/games/bin:CUDA_ROOT:CUDA_ROOT sudo su and then echo $PATH gives -> /sbin:/bin:/usr/sbin:/usr/bin There is no CUDA_ROOT.

Re: [PyCUDA] nvcc not in path

You mean the .bash_profile in the root/ path? Because i tried to do (in root/.bash_profile): # This file is sourced by bash for login shells. The following line # runs your .bashrc and is recommended by the bash info pages. [[ -f ~/.bashrc ]] && . ~/.bashrc PATH=$PATH:$HOME/bin export PATH but still the same. -- View this message in context: http://pycuda.2962900.n2.nabble.com/nvcc-not-in-path-tp7574709p7574719.html Sent from the PyCuda mailing list archive at Nabble.com.

Problems with GPU arrays

by Andrew Miller

Hello, While working with PyCuda, I've noticed that several GPU array functions seem to be giving errors, that should work fine. * * *These are using one-dimensional arrays.* __imul__ works fine for an array times a scalar, but has errors when an array is multiplied by another array (this was recently fixed in PyOpenCL) __pow__ seems to have problems with complex arrays. If I take a complex array, a, and say a**2, I get an error. This works fine with floats though. I'm fairly certain that these are just bugs, since both work fine in PyOpenCL. Is that the case? Thanks! -Andrew Miller
