ubuntu 源码编译libtorch
生活随笔
收集整理的這篇文章主要介紹了
ubuntu 源码编译libtorch
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
## pytorch/libtorch qq群： 1041467052
有一點兒感悟就是：
一定要去官網找一手資料，百度出來的都是個人根據官網來的，這個就隨便看看了。
官網：https://github.com/pytorch/pytorch
首先我跑的是pytorch 1.3版本的，conda安裝好的，現在需要源碼編譯。按照官網的流程，需要先安裝依賴包。
我是切換到pytorch1.3的conda虛擬環境進行的：這里是官網的教程：
其中，git clone --recursive https://github.com/pytorch/pytorch 是下載的最新版本，而我需要1.3的。
下載完成后：
會出來：
v0.1.1 v0.1.10 v0.1.11 v0.1.12 v0.1.2 v0.1.3 v0.1.4 v0.1.5 v0.1.6 v0.1.7 v0.1.8 v0.1.9 v0.2.0 v0.3.0 v0.3.1 v0.4.0 v0.4.1 v1.0.0 v1.0.0a0 v1.0.1 v1.0rc0 v1.0rc1 v1.1.0 v1.1.0a0 v1.2.0 v1.2.0a0 v1.3.0 v1.3.0a0 v1.3.1 v1.4.0 v1.4.0a0 v1.4.1 v1.5.0 v1.5.0-rc1 v1.5.0-rc2 v1.5.0-rc3 v1.5.0-rc4 v1.5.0-rc5然后敲：
git checkout v1.3.1然后再：
git submodule sync git submodule update --init --recursiveexport CMAKE_PREFIX_PATH=${CONDA_PREFIX:-"$(dirname $(which conda))/../"} python setup.py install然后是漫長的等待
好久之后，沒有報錯，然后我不知道我需要的庫生成在哪里，然后往上翻日志：
找到
-- CMAKE_INSTALL_PREFIX : /data_2/everyday/0429/pytorch/torch
恩，安裝到了目錄torch下面了。
然后用測試代碼，cmakelist，可以加載模型。應該是可以了。
還有注意就是cuda這些環境需要配置好。

以下是20200901更新：
按照這邊的流程今天又編譯了pytorch1.1.0 cuda10的libtorch庫，把流程寫在這里：
首先是anaconda環境snake_cuda10，這個環境snake_cuda10是已經能夠跑通一個git倉庫的工程，是基于pytorch1.0，cuda10的conda環境下的：:
命令1：
?source activate snake_cuda10
?conda install numpy ninja pyyaml mkl mkl-include setuptools cmake cffi typing_extensions future six requests dataclasses
這里是按照官網上面的安轉依賴，會提示一些網絡問題：
CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/linux-64/mkl-2020.2-256.tar.bz2>
Elapsed:

HTTP errors are often intermittent, and a simple retry will get you on your way
簡單的重試就可以。
命令2：
conda install -c pytorch magma-cuda100
git clone --recursive https://github.com/pytorch/pytorch
漫長的等待

漫長的等待+1
2021年09月01日15:59:13更新
https://oldpan.me/archives/pytorch-build-simple-instruction
只安裝libtorch庫:創建build文件夾，在里頭執行python ../tools/build_libtorch.py
python的安裝方式并不是單獨利用Cmake進行構建的，而是結合了python端的setuptools搭配cmake進行構建，pytorch的項目還是比較龐大的，所以編譯代碼也是老長，我們主要看看編譯過程中的環境變量即可：
在setup.py里面：
```
# Environment variables you are probably interested in: # # DEBUG # build with -O0 and -g (debug symbols) # # REL_WITH_DEB_INFO # build with optimizations and -g (debug symbols) # # MAX_JOBS # maximum number of compile jobs we should use to compile your code # # NO_CUDA # disables CUDA build # # .... # .... # # Environment variables for feature toggles: # # NO_CUDNN # disables the cuDNN build # # NO_FBGEMM # disables the FBGEMM build # # NO_TEST # disables the test build # # NO_MIOPEN # disables the MIOpen build這些編譯變量根據我們的需要在執行python setup.py install使用，如果你不想編譯CUDA，則NO_CUDA=1 python setup.py install.
執行以上語句我們就可以進行編譯了。
```
2021年09月01日16:56:26再次編譯libtorch1.6，cuda10.2

我cuda10.2， cudnn8.0.
看了cmake/public/cuda.cmake:170。 里面寫法就是獲取cudnn.h剛開始的頭文件里面編寫的版本號，可是我在cudnn.h里面沒有找到，7點多版本是有的。于是是把cudnn8刪掉，下載了cudnn7.6.5可以。
但是后續又出現錯誤了，一大堆

specialization with C linkagetemplate<>好像是nccl的，天啊！無解。
然后百度其他的，發現可以直接編譯libtorch。
只安裝libtorch庫:創建build文件夾，在里頭執行python ../tools/build_libtorch.py
然后執行這個命令沒有報錯。成功編譯出庫出來了。
總結
以上是生活随笔為你收集整理的ubuntu 源码编译libtorch的全部內容，希望文章能夠幫你解決所遇到的問題。
