ubuntu 23.04从源码编译安装rocm运行tensorflow-rocm
因为ubuntu22.04的RDP不支持声音转发，所以下载了ubuntu23.04.但官方的rocm二进制包最高只支持ubuntu22.04，不支持ubuntu 23.04，只能自己从源码编译虽然有网友告诉我可以用docker运行rocm。但是我已经研究了好几天，沉没成本太多，无奈只能继续硬着头皮研究，终于搞定了。记录下结果，可能有遗漏，顺序也可能不对，仅供参考。如果CMAKE有错误可以试试添加或者删除-DCMAKE_PREFIX_PATH="/opt/rocm/",毕竟为了避免冲突，rocm的库独立于系统主库了。
首先，要明确一点，rocm安装的位置在/opt/rocm/目录下，而rocm-llvm工具链安装目录为/opt/rocm/llvm这个可以通过解包官方的deb包来知道。注意不要把/opt/rocm/llvm目录下的东西安装到/opt/rocm/目录下不然会报错，注意这个-DCMAKE_INSTALL_PREFIX="/opt/rocm/"参数指定安装位置（默认是/usr/local）。
如果不小心装错位置了，可以使用命令
sudo grep -lrIZ "https://llvm.org/LICENSE.txt " . | sudo xargs -0 rm -f --
删除LLVM/opt/rocm/lib目录下相关的库。
一、编译安装llvm-rocm工具链
安装这个工具链之前，确保已经有其他工具链已经被安装。可以是llvm也可以是gnu。建议第一次make install的时候不要加sudo，避免装错位置。
mkdir -p /opt/rocm/llvm
cd
git clone https://github.com/RadeonOpenCompute/llvm-project.git -b amd-stg-open
cd
mkdir build
cd build/
cmake -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang;lld"
-DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi;libunwind;compiler-rt"
-DLLVM_TARGETS_TO_BUILD='AMDGPU;X86'
-DCMAKE_INSTALL_PREFIX=/opt/rocm/llvm
../llvm
sudo make install
cd ../amd/device-libs
mkdir build
cmake \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_PREFIX_PATH="/opt/rocm/llvm" \
-DCMAKE_INSTALL_PREFIX=/opt/rocm/ \
..
sudo make install
cd ../amd/comgr
mkdir build
cmake \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_PREFIX_PATH="/opt/rocm/llvm;/opt/rocm/" \
-DCMAKE_INSTALL_PREFIX=/opt/rocm/ \
..
sudo make install
二、编译安装hip工具链
参考：https://github.com/ROCm-Developer-Tools/HIP/blob/develop/docs/developer_guide/build.md
sudo apt-get install -y libelf-dev
export ROCM_BRANCH=rocm-5.7.x
git clone -b "$ROCM_BRANCH" https://github.com/ROCm-Developer-Tools/clr.git
git clone -b "$ROCM_BRANCH" https://github.com/ROCm-Developer-Tools/hip.git
git clone -b "$ROCM_BRANCH" https://github.com/ROCm-Developer-Tools/HIPCC.git hipcc
export CLR_DIR="$(readlink -f clr)"
export HIP_DIR="$(readlink -f hip)"
export HIPCC_DIR="$(readlink -f hipcc)"
cd "$HIPCC_DIR"
mkdir -p build; cd build
cmake ..
make -j4
cd "$CLR_DIR"
mkdir -p build; cd build
cmake -DHIP_COMMON_DIR=$HIP_DIR -DHIP_PLATFORM=amd -DCMAKE_PREFIX_PATH="/opt/rocm/" -DCMAKE_INSTALL_PREFIX=/opt/rocm/ -DHIPCC_BIN_DIR=$HIPCC_DIR/build -DHIP_CATCH_TEST=0 -DCLR_BUILD_HIP=ON -DCLR_BUILD_OCL=OFF ..
make -j$(nproc)
sudo make install
三、编译安装rocm-runtime
参考：https://github.com/RadeonOpenCompute/ROCR-Runtime/tree/master/src
git clone https://github.com/RadeonOpenCompute/ROCT-Thunk-Interface.git
mkdir -p ROCT-Thunk-Interface/build
cd ROCT-Thunk-Interface/build
cmake -DCMAKE_INSTALL_PREFIX=/opt/rocm ..
sudo make install
git clone https://github.com/RadeonOpenCompute/ROCR-Runtime.git
mkdir -p src/build
cd src/build
cmake -DCMAKE_INSTALL_PREFIX=/opt/rocm ..
sudo make install
四、编译安装rCCL
时间比较长占用内存六十多个G，如果内存不够的话可以加大swap文件或者使用zRAM。
sudo apt install zram-config
sudo nano /usr/bin/init-zram-swapping
把里面的mem=$((totalmem / 2 * 1024)) 改为mem=$((totalmem * 2 * 1024))
然后reboot重启，这样就能使用自身内存两倍的zram
git clone https://github.com/RadeonOpenCompute/rocminfo.git -b rocm-5.7.x
cd rocminfo/
mkdir -p build
cd build
cmake -DCMAKE_PREFIX_PATH=/opt/rocm ..
sudo make install
python3 -m pip install CppHeaderParser
git clone https://github.com/RadeonOpenCompute/rocm_smi_lib.git
cd rocm_smi_lib/
mkdir -p build
cd build
cmake ..
sudo make install
git clone https://github.com/ROCmSoftwarePlatform/rccl.git
cd rccl
sudo ./install.sh -i
五、设置环境变量
参考：https://docs.amd.com/en/docs-5.1.3/deploy/linux/os-native/install.html
sudo tee --append /etc/ld.so.conf.d/rocm.conf <<EOF
/opt/rocm/lib
/opt/rocm/lib64
EOF
sudo ldconfig
六、安装tensorflow-rocm测试
sudo apt install tensorflow-rocm scikit-learn scipy matplotlib
然后测试
可能遇到的错误：
Could not find NUMA using the following names: numa
解决办法:
apt-get install libnuma-dev
rocm_smi/rocm_smi.h’ file not found
解决办法: 参考步骤四安装smi库
importError: cannot import name ‘np_utils’ from ‘keras.utils’
解决办法: 修改代码，直接ffrom keras import utils 然后 utils.to_categorical(…)
librccl.so.1: cannot open shared object file: No such file or directory
解决方法：完成步骤四
lang: error: invalid target ID ‘gfx941’; format is a processor name followed by an optional colon-delimited list of features followed by an enable/disable sign (e.g., ‘gfx908:sramecc+:xnack-’)
解决方法：完成步骤一、安装最新rocm-llvm工具链且确保设置-DCMAKE_PREFIX_PATH="/opt/rocm/"
Could not find a configuration file for package “hsa-runtime64”
解决方法：完成步骤三
