pip 安装

在FreeBSD系统下pip安装pytorch，报错

安装pyproject

 pip install pyproject

再pip 安装pytorch还是同样的报错：

Building wheels for collected packages: pytorch

查找帮助说:

运行编译过程中出现错误，并提示“Too many arguments to functions call, expected....”的信息:

遇到这种情况时，该如何解决呢？解决方法是将属性“Enable Strict Checking of objc_msgSend Calls”的值设置成“No”，即TARGETS——>项目——>Build Settings——>Apple LLVM 6.0 - Preprocessing——>Enable Strict Checking of objc_msgSend Calls

pkg安装

到pkg里发现有现成的pytorch包，于是pkg 安装：pkg install pytorch

报错冲突：

根据提示，是pytorch和fmt文件冲突了。删除libfmt包试试

pkg remove libfmt

删除之后再安装pytorch，会自动再安装上libfmt并继续报冲突。

pip安装python39-pytorch包

pkg install py39-pytorch

安装好之后导入torch报错：

>>> import torch
Traceback (most recent call last):File "<stdin>", line 1, in <module>File "/usr/local/lib/python3.9/site-packages/torch/__init__.py", line 237, in <module>from torch._C import *  # noqa: F403

源码编译安装

下载源代码

git clone --depth 2 https://github.com/pytorch/pytorch

设置环境变量

# 直接在终端中输入即可，重启需要重新输入
export USE_CUDA=0
export USE_DISTRIBUTED=0
export USE_MKLDNN=0
export MAX_JOBS=8

编译

cd pytorch
mkdir build
cd build
cmake ..
make -j 8

报错

配置这里就没有过去。这个报错指向了这里

CMake Error at third_party/FP16/CMakeLists.txt:94 (ADD_SUBDIRECTORY):
  The source directory

    /home/skywalk/github/pytorch/third_party/psimd

  does not contain a CMakeLists.txt file.

原来psimd目录是空的啊，删除这个目录，然后执行：

third_party]$ git submodule update --init --recursive

问题解决。后面发现foxi 、 sleef目录也是空的，同样处理，先删除目录，再git submodule update

现在终于cmake成功了，然后make：

make install -j 8

编译到40%左右的时候报错

更新源代码：

~/github/pytorch]$ git pull

还是这个报错

改方法，python安装

python setup.py develop --cmake

报错：

又重新安装下，报错：

ports 编译安装

 安装时会有一些库安装的比较慢，可以采取各种方法改进，比如手工下载文件然后放到/usr/ports/distfiles目录里。pkg手动安装一些依赖库，比如：

pkg install psimd
pkg install kineto

cd /usr/ports/misc/pytorch 
make install 
===>  Installing for pytorch-2.1.2
===>  Checking if pytorch is already installed
===>   Registering installation for pytorch-2.1.2

*** Error code 1Stop.

还是安装的时候报冲突
