spconv1.2.1安装时出现的错误

在使用python setup.py bdist_wheel 时出现如下错误：

问题详述：

描述： 该问题是在你安装spconv1.0/1.2.1时，执行python setup.py bdist_wheel时，编译一半出现的问题。

可能1：此问题说明spconv安装缺文件，从官方下载下来的spconv1.2.1，文件夹下的third_party/pybind11是空的，需要自己手动去下载。

pybind11链接：https://github.com/pybind/pybind11/tree/3b1dbebabc801c9cf6f0953a4c20b904d444f879

可能2：电脑是30系列显卡时，需要安装CUDA11.x，属于高版本，spconv需要安装2.x。
遇见问题：

原因:算力太高不支持，
解决方法：

export TORCH_CUDA_ARCH_LIST="8.0"
source ~/.bashrc

每台主机问题多种多样，出现这种问题很多情况下是版本不适配。

可能3：今天又碰着了一回，是安装spconv1.0时候，以下给出一个github的解决方案：
还没试，之后试一下。

conda create --name spconv python=3.7 pytorch=1.4 cudatoolkit=10.1 cudatoolkit-dev=10.1 cmake --channel pytorch

conda activate spconv

conda install cudnn

git clone https://github.com/traveller59/spconv --recursive

cd spconv

git checkout 8da6f967fb9a054d8870c3515b1b44eca2103634

git am <path_to_hotfixes>/0001-fix-problem-with-torch-1.4.patch

git am <path_to_hotfixes>/0001-Allow-to-specifiy-CUDA_ROOT-directory-and-pick-corre.patch

CUDA_ROOT=<path_to_your_conda_installation>/envs/spconv python setup.py bdist_wheel

cd dist/

pip install *

可能4：
不乏有文件错误的可能，这里提供一个我亲测有效的文件：
用于spconv1.2.1的安装，目前亲测有效
可能5：

把/spconv/build/文件夹里面的环境都删除，重新安装一遍，有可能是之前某个电脑安装的残留，导致现在安装不了。
可能6：
今天又是一个新问题，这次使用A100，cuda11.5，刚编译就报错

然后我发现是gcc版本的问题，我将gcc-9和g+±9换到了gcc-11和g+±11，就解决了报错。
具体的更换的方法如下：
①移除过去版本

sudo rm /usr/bin/gcc
sudo rm /usr/bin/g++

②安装新版本

sudo apt-get install gcc-11 # 不行的话用这个：sudo apt-get install gcc
sudo apt-get install g++-11

③添加新的软连接（快捷方式）

sudo ln -s /usr/bin/gcc-11 /usr/bin/gcc
sudo ln -s /usr/bin/g++-11 /usr/bin/g++

gcc -v再检查一下是否更换正确即可。
卒，可能6的问题没解决，网上的说法是gcc或者cudnn出了问题，我没排查出来，这里有一个更加简单的解决方法：

我们可以将spconv-1.2.1的语法换成2.x版本的，主要替换的有：
①索引：

#spconv1.x版本
import spconv
a = spconv.SparseModule()
#spconv2.x版本
import spconv.pytorch as spconv
a = spconv.SparseModule()

②卷积

#spconv1.x版本
from spconv import SparseConv3d, SubMConv3d
#spconv2.x版本
from spconv.pytorch.conv import (SparseConv2d, SparseConv3d, SparseConvTranspose2d,
                         SparseConvTranspose3d, SparseInverseConv2d,
                         SparseInverseConv3d, SubMConv2d, SubMConv3d)

③SparseTensor特征传递

#spconv1.x版本
out.features = self.bn1(out.features)
#spconv2.x版本
out = out.replace_feature(self.bn1(out.features))

例如对centerformer中的backbone/scn.py的更改方法为：

        out =out.replace_feature(self.bn1(out.features))
        out =out.replace_feature(self.relu(out.features))

        out = self.conv2(out)
        out = out.replace_feature(self.bn2(out.features))

        if self.downsample is not None:
            identity = self.downsample(x)

        out= out.replace_feature(out.features+identity.features)
        out = out.replace_feature(self.relu(out.features))

具体更改方法详见：

这个问题是由于spconv版本和torch版本不匹配导致的，报错的spocnv的版本是1.2.1，torch的版本是1.10.0-cu111。

我们只需要将torch的版本从torch1.10.0-cu111降到torch1.9.0-cu111即可（torchvision也需要从0.11.0降到0.10.0)，之后再import spconv就没问题了。

如果还遇见上述问题，我还会更新。
