使用Theano加载库gpuarray时出错 [英] Error loading library gpuarray with Theano
问题描述
我正在尝试运行 我需要使用 我可以无错误地导入
警告:完全有可能这都是错误的，而导致问题的实际原因实际上是-您怀疑-您的gpu驱动程序. 我在Windows 10上的gpuarray遇到了同样的问题.
最后，我通过以下方式解决了该问题: 通过anaconda安装theano: 在使用linux时:此错误消息基本上表示它不起作用，请不要问我为什么，并且大多数情况下会显示您的设置是否有误(例如，使用了不同的编译器编译python和theano或不兼容的cuda版本) 我建议您更新到cuda 8.0并通过anaconda重新安装python环境(以防万一) 附带说明:我从文档中测试了您的示例脚本，至少可以正常工作.... Windows用户注意事项:切勿尝试在路径中有空格的位置安装Anaconda ...一切看起来都很好...直到theano开始查找和编译错误. /p>
关于 通常您只需设置环境变量: 但该测试的习惯是，如果无法加载该库，则您未指定设备... I am trying to run this script to test Theano's use of my GPU and get the following error: I need to use the I can import
Warning: its entirely possible that this is all wrong and the actual reason for your problem is in fact - as you suspect - your gpu driver. I had the same issue with gpuarray on Windows 10.
In the end I solved it by: install theano through anaconda: As you are using linux: This error message basically means It didn't work, don't ask me why And is mostly shown if something with your setup is wrong (e.g. different compilers used for compiling python and theano, or incompatible cuda version) I would recommend to update to cuda 8.0 and to reinstall your python environment over anaconda (just in case) On a side note: I tested your example script from the docu and at least that is working.... Note for windows users: Never try to install Anaconda in a location where you have spaces in the path... Everything looks fine ... until theano starts having trouble finding and compiling things. Note regarding the Normally you just set the environment variable: BUT The test has the habit of saying you didn't specify a device if the library couldn't be loaded... 这篇关于使用Theano加载库gpuarray时出错的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！nvidia-381驱动程序，因为我的GPU是1080 ti，并且与nvidia-375不兼容.我不确定这是否重要，但是如果安装nvcc后重新安装381，则安装nvcc会覆盖381并导致一些错误，因此我无法使用nvcc. pygpu，但是如果运行pygpu.test()，则会出现以下错误，并且我不知道如何在没有nvcc的情况下指定DEVICE变量. ======================================================================

nvidia-381 driver since my GPU is a 1080 ti and is not compatible with nvidia-375. I'm not sure if that matters but installing nvcc overwrites 381 and causes some errors if I reinstall 381 after setting up nvcc so I can't use nvcc. pygpu without errors but if I run pygpu.test() I get the following error and I don't know how to specify the DEVICE variable without nvcc. ======================================================================
