I have installed Torch by following the instructions here, which comes with Lua 5.1, but Lua 5.3 was installed previously on my system. Now when I try to run a program using Torch, I get the following error messages:
/Users/Marcel/torch/install/share/lua/5.1/trepl/init.lua:389: module 'Settings.arguments' not found:No LuaRocks module found for Settings.arguments
no field package.preload['Settings.arguments']
no file '/usr/local/share/lua/5.1/Settings/arguments.lua'
no file '/usr/local/share/lua/5.1/Settings/arguments/init.lua'
It would seem as if Torch is looking for its own version of Lua in the system directories, which only contain the previously installed version. Is there any way to fix this, or must I uninstall the Lua 5.3?
Thanks!
Simply change TORCH_LUA_VERSION value to LUAXX, as it is explain in installation instructions with 5.2 version. For 5.3 version, use LUA53:
git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch
# clean old torch installation
./clean.sh
# optional clean command (for older torch versions)
# curl -s https://raw.githubusercontent.com/torch/ezinstall/master/clean-old.sh | bash
# https://github.com/torch/distro : set env to use lua
TORCH_LUA_VERSION=LUA53 ./install.sh

I am trying to create a class diagram with sphinx. For this I created a virtual environment in Pycharm and added this to conf.py:
extensions = ['sphinx.ext.autodoc','sphinx.ext.inheritance_diagram']
In my spamfilter.rst file I added the following lines:
Diagrams
=================
.. inheritance-diagram:: spamfilter
The output is not a diagram and looks like this.
The following warning is displayed:
WARNING: dot command 'dot' cannot be run (needed for graphviz output), check the graphviz_dot setting
When I look into the folder C:\Users\Name\PycharmProjects\documentation\venv\Lib\site-packages\graphviz, there is a dot.py file, so I do not understand what is wrong. A similar question for Mac OS has been asked here. I tried the solution but it seems like it only works for Mac, because when I paste export PATH=$PATH:~/opt/bin to the Pycharm Terminal, it tells me that the command export could not be found. Honestly I have problems understanding why sometimes you can just use packages and other times they cannot be found even when they are installed, I am self-taught and a beginner.
The "pip install graphviz" command installs a Python package that provides an interface to Graphviz (https://pypi.org/project/graphviz). This package is not required by Sphinx.
In order to create inheritance diagrams with Sphinx, the actual Graphviz toolkit (including dot.exe) must be installed. See https://www.graphviz.org.
If dot.exe is not in the PATH, you can use the graphviz_dot configuration option.
I had the same problem where rendering a C4 model with PlantUML didn't work in the IDE (PyCharm 2022.2.1 Pro) on a newer M1 MacOS Monterey. I had it working on a Big Sur intel Mac prior to the upgrade with no extra effort, so the chip change caused me to go down a lot of paths with Rosetta and so on that were all unsuccessful.
The error was:
Dot Executable: /opt/local/bin/dot
File does not exist
Cannot find Graphviz.
Graphviz was installed correctly, and dot was on my path, but it wasn't in /opt/local/bin/dot. Since it was in /opt/homebrew/bin/dot, all I needed to do was link the actual file with the path it was searching for:
cd /opt
sudo ln -s homebrew local
et voilà, PyCharm is now correctly rendering the puml in the IDE.
I want to install MongoDB C++ Driver, so first is mongocxx
I follow this installation:
http://mongocxx.org/mongocxx-v3/installation/
but I can not pass step 4
when I run this in mongo-cxx-driver/build
sudo cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
it shows
-- Auto-configuring bsoncxx to use MNMLSTC for polyfills since C++17 is inactive
CMake Error at src/mongocxx/CMakeLists.txt:37 (find_package):

second question,
Step 2: Choose a C++17 polyfill how can I set MNMLSTC/core?
does anyone can help me,I already trap here for a long time ?
my env:
mongo-c-driver 1.15.1
libmongoc-1.0
mongocxx-3.4.x
Cmake is complaining about not finding a package configuration file (xxx.cmake), probably because you didn't build libmongoc/libbson.
I've tried to reproduce your issue and hit the same problem when I only installed them (apt-get install), so my suggestion is that you get the sources and build them as described at: http://mongoc.org/libmongoc/current/installing.html
Here's the list of commands (with the latest version of mongo-c-driver=1.15.1) which I just tried and worked fine:
wget https://github.com/mongodb/mongo-c-driver/releases/download/1.15.1/mongo-c-driver-1.15.1.tar.gz
tar xzf mongo-c-driver-1.15.1.tar.gz
cd mongo-c-driver-1.15.1
mkdir cmake-build
cd cmake-build
cmake -DENABLE_AUTOMATIC_INIT_AND_CLEANUP=OFF ..
make
sudo make install
At this point you can go back into mongocxx/build and run again the command you were stuck at:
cd ../../mongo-cxx-driver/build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
I am trying to build a C++ code on Mac. I am using CMake for my setup. This is my file (note, I get an error with python3.7, python37, python, but more on that below):
find_package(Boost COMPONENTS python3.7)
message("Includes: ${Boost_INCLUDE_DIRS} ${Python3_INCLUDE_DIRS}")
I get the following error:

Includes: /usr/local/include /usr/local/Cellar/python/3.7.4_1/Frameworks/Python.framework/Versions/3.7/include/python3.7m
I am using the latest Homebrew
brew --version
Homebrew 2.1.12
Homebrew/homebrew-core (git revision 5b0c; last commit 2019-10-06)
And have loaded the available boost formulae.
brew list | grep boost
boost
boost-python
boost-python3
Looking under /usr/local/lib/cmake/ I see most of the boost libraries mentioned, but boost_python and boost_numpy are missing. I checked the online formulae definitions and boost does indeed include all the cmake setups in that directory, but boost_python3 does not include any.
Am I missing some package? Is there a portable way to setup this so that it automatically finds the libboost_python37.* files?
Because there is no python3.7 component. This component is called python37, at least for CMake 3.16 and earlier:
Note that Boost Python components require a Python version suffix (Boost 1.67 and later), e.g. python36 or python27 for the versions built against Python 3.6 and 2.7, respectively. This also applies to additional components using Python including mpi_python and numpy. Earlier Boost releases may use distribution-specific suffixes such as 2, 3 or 2.7. These may also be used as suffixes, but note that they are not portable
I have been trying some different java compilers over the weekend and decided to stick with javac this morning. I then proceeded to clean up the mess that was caused by my testing and removed every last trace of java and did a fresh 'apt-get install openjdk-6-jdk' after autoremove and autoclean.
The following weirdness was then encountered:
tarskin#5-PARA-11-0120:~$ javac
The program 'javac' can be found in the following packages:
* openjdk-6-jdk
* ecj
* gcj-4.4-jdk
* gcj-4.6-jdk
* gcj-4.5-jdk
* openjdk-7-jdk
Try: sudo apt-get install <selected package>
I had allready installed openjdk but i tried it anyhow yielding:
tarskin#5-PARA-11-0120:~$ sudo apt-get install openjdk-6-jdk
[sudo] password for tarskin:
Reading package lists... Done
Building dependency tree
Reading state information... Done
openjdk-6-jdk is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
tarskin#5-PARA-11-0120:~$
I know i must be doing something stupid but I have no idea what, if anyone else could give a pointer in the right direction that would be very much appreciated...
Cheers
EDIT: Found some other weird aspects about the 'new' instance of my java distro, it doesn't seem to recognise for example 'Pattern' or 'Matcher' that should be coming from the regex import shrugs.
TL;DR: install java-1.6.0-openjdk-devel
I had a similar issue on Fedora, but used rpm -q -l to list the contents of the (pre-installed) java-1.6.0-openjdk package, and discovered that it doesn't include javac. It is in fact only a JRE, not a JDK, as implied by the installation instructions on http://openjdk.java.net/install/ . To get javac, I installed java-1.6.0-openjdk-devel . Not exactly what I expected, because the usual packaging conventions would indicate that is the package for doing openjdk development (i.e., working on the JVM), not for developing programs with it.
Basically, openjdk's package naming doesn't follow either standard Java conventions (would require calling it a JRE somewhere), or standard Linux packaging conventions (using -devel indicates it is used for developing the package w/o -devel itself).
As per http://openjdk.java.net/install/, to install the OpenJDK-6 JRE only:
$ sudo apt-get install openjdk-6-jre
To install the full JDK:
$ sudo apt-get install openjdk-6-jdk
Check /etc/alternatives and /usr/bin. One or both will contain links to old Java versions which you had installed. When those links are broken, you can get the error message above.
To update the links after installing a new version of Java, try update-alternatives
First to check if javac is installed try to look for that file:
1. locate javac
2. or find / -name javac
And also you can check at this website with instrucions on how to install java on Ubuntu (i suppose you are on ubuntu):
http://openjdk.java.net/install/
You can also check:
http://packages.ubuntu.com/hardy/i386/openjdk-6-jdk/filelist for the files installed by the pacakge, and you can notice that javac should be installed.
Maybe you also need to run:
Open the terminal and run this command to install OpenJDK 7.0 on Ubuntu Oneiric:
sudo update-alternatives --config java
I'm trying to use CMake to build generate the make file for a project of mine that uses Lua. When I run make I get this error:
/path/to/my/project/luaudio/luaudio.c:1:17: fatal error: lua.h: No such file or directory
In the CMakeLists.txt file, I have the following lines, which I thought would do it, but apparently they're not enough:
find_package(Lua51 REQUIRED)
set(Luaudio_INCLUDE_DIRS ${Luaudio_SOURCE_DIR} ${Lua51_INCLUDE_DIRS} PARENT_SCOPE)
include_directories(${Luaudio_INCLUDE_DIRS})
Lua51_Include_Dirs appears to be empty (attempting to run it though the message command doesn't print anything) so I suspect that it just can't find it. Do I need to specify where to look for Lua? I was under the impression that the whole point of find_package was that it would look in a set a predefined places so that I don't need to specify where it is specifically.
(This is on an Ubuntu machine and I do have the Lua packages installed.)
install lua bin:
sudo apt-get install lua5.1
install lua lib:
sudo apt-get install lua5.1-dev
Exploring FindLua51.cmake from cmake 2.8 I found that it sets LUA_INCLUDE_DIR variable instead of Lua51_INCLUDE_DIRS. So cmake code should be
find_package(Lua51 REQUIRED)
set(Luaudio_INCLUDE_DIRS ${Luaudio_SOURCE_DIR} ${LUA_INCLUDE_DIR} PARENT_SCOPE)
include_directories(${Luaudio_INCLUDE_DIRS})
for Ubuntu 14.04
sudo apt install lua5.2;
sudo apt install liblua5.2-dev;
