Question

我正在尝试设置deepmind / dqn https://github.com/deepmind/dqn的环境，我运行./install_dependencies.sh进行安装

LuaJIT and Torch 7.0
nngraph
Xitari
AleWrap

首先。但是我得到了

/home/dqn/torch/bin/luajit: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory

 - => Torch7 has been installed successfully

   Installing nngraph ... /home/dqn/torch/bin/luajit: error while
   loading shared libraries: libreadline.so.7: cannot open shared object
   file: No such file or directory Error. Exiting.

install_dependencies.sh是：

# Install dependencies for Torch:
sudo apt-get update
sudo apt-get install -qqy build-essential
sudo apt-get install -qqy gcc g++
sudo apt-get install -qqy cmake
sudo apt-get install -qqy curl
sudo apt-get install -qqy libreadline-dev
sudo apt-get install -qqy git-core
sudo apt-get install -qqy libjpeg-dev
sudo apt-get install -qqy libpng-dev
sudo apt-get install -qqy ncurses-dev
sudo apt-get install -qqy imagemagick
sudo apt-get install -qqy unzip
sudo apt-get update


echo "==> Torch7's dependencies have been installed"





# Build and install Torch7
cd /tmp
rm -rf luajit-rocks
git clone https://github.com/torch/luajit-rocks.git
cd luajit-rocks
mkdir -p build
cd build
git checkout master; git pull
rm -f CMakeCache.txt
cmake .. -DCMAKE_INSTALL_PREFIX=$PREFIX -DCMAKE_BUILD_TYPE=Release
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi

path_to_nvcc=$(which nvcc)
if [ -x "$path_to_nvcc" ]
then
cutorch=ok
cunn=ok
fi

echo ""
echo "=> Torch7 has been installed successfully"
echo ""


echo "Installing nngraph ... "
$PREFIX/bin/luarocks install nngraph
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
echo "nngraph installation completed"

echo "Installing Xitari ... "
cd /tmp
rm -rf xitari
git clone https://github.com/deepmind/xitari.git
cd xitari
$PREFIX/bin/luarocks make
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
echo "Xitari installation completed"

echo "Installing Alewrap ... "
cd /tmp
rm -rf alewrap
git clone https://github.com/deepmind/alewrap.git
cd alewrap
$PREFIX/bin/luarocks make
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
echo "Alewrap installation completed"

echo
echo "You can run experiments by executing: "
echo
echo " ./run_cpu game_name"
echo
echo " or "
echo
echo " ./run_gpu game_name"
echo
echo "For this you need to provide the rom files of the respective games (game_name.bin) in the roms/ directory"
echo

当我测试代码./run_gpu {game_name}时，我得到了：

../torch/bin/luajit: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory

当我运行ldconfig -p | grep readline 我的版本低于6

libreadline.so.6 (libc6,x86-64) => /lib/x86_64-linux-gnu/libreadline.so.6
libreadline.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libreadline.so
libguilereadline-v-18.so.18 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libguilereadline-v-18.so.18
libguilereadline-v-18.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libguilereadline-v-18.so

但是我无法通过以下方式安装libreadline7：sudo apt-get install libreadline7-dev

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libreadline7-dev

我该如何解决libreadline7的安装？

Answer 1

这主要是由于蟒蛇造成的，请尝试从PATH中禁用它

Answer 2

要解决此依赖性，您需要手动安装上述软件包。转到ubuntu商店并搜索软件包。

https://packages.ubuntu.com/search?suite=default&section=all&arch=any&keywords=libreadline7&searchon=names

这将列出包装信息。单击包装说明中提供的超链接。在这种情况下：

https://packages.ubuntu.com/bionic/libreadline7

单击您所在地区的任何链接。这将开始下载该软件包的debian文件。

一旦获得了debian文件，您只需使用dpkg命令进行安装

例如：

sudo dpkg -i Desktop / libreadline7_7.0-3_amd64.deb

加载共享库时出错：libreadline.so.7：无法打开共享库文件：没有这样的文件或目录
