I then tried to install by trying to first downloading Wheels from Here and Also this, The Wheels were Not correct for my platform(it appears). Then, I tried my best to follow steps on the Kaggle site : https://www.kaggle.com/questions-and-answers/31960. (Using Git Bash).
When that failed. I managed to download the Tar pkg on my local PC, and tried to run the install I tried to run an install: python setup.py install

I was stuck on the following error:

It seems that Pyinstaller can't find the xgboost.dll, VERSION files. So you need to add them manually to your output package. I also suggest you use a try/except block to see what is going on. Suppose this simple example:

QUESTION

Visual C++ : XGBoost does not work when called from a DLL

Asked 2018-Aug-10 at 12:26

I have a requirement to use XGBoost within a Visual C++ project DLL. I have been able to download and build the XGBoost source using VC++ and CMake.

When I include the XGBoost code in a test console application, it works fine.

However, when I try to replicate what I've done with the console application in a DLL project, it won't compile. I am struggling to even use a basic XGBoost type within the project.

I suspect the problem is my ignorance with DLL projects and would appreciate your help.

Here's what's happening in my DLL project: When I use the following include as the very first line in a cpp class file, it compiles:
#include

With it compiling, if I try to use a simple type defined in this include file, the build fails with the following message:
...\dll_test\xgb_driver.cpp(20): error C2065: 'BoosterHandle': undeclared identifier

This is the line that causes the error:
BoosterHandle my_handle;

"BoosterHandle" is in fact defined in

When I put the include below any other include, I get the following error messages:
1>c:\tools\src\xgboost\include\xgboost\c_api.h(29): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

1>c:\tools\src\xgboost\include\xgboost\c_api.h(29): error C2146: syntax error: missing ';' before identifier 'bst_ulong'

Below is a little more information on what I did to get XGBoost working with a console app and how I created the DLL project.

=-=-=-=-=-=

Here's what I did to use XGBoost with a console. Everything about it seems to work. I've tested the model predictions, and they are consistent with what I'm seeing in R.

Using the documentation found here: https://xgboost.readthedocs.io/en/latest/build.html

I downloaded the XGBoost source and built it using CMake and Visual Studio 2015.
Under Project > Linker > Input > Additional Dependencies, I added the xgboost.lib file
Under Project > Linker > General > Additional Library Directories I added a reference to ...\xgboost\build\Release
Under Project > VC++ Directories > Include Directories I added the path to ...\xgboost\rabit\include and ...\xgboost\include
I put the xgboost.dll in the directory where the .exe is generated.

From here, it was smooth sailing.

=-=-=-=-=-=

Here's what I've done to create a Visual C++ DLL Project:

After choosing File > New > Project, I select an ATL DLL Project (this is part of the project requirement).

For the XGBoost include to the project, I repeated steps 1-5 above, but placed the xgboost.dll file where the project DLL would be generated.

Here is the source for the header file for the simple class I have created:

With the help of CristiFati, I believe this question has been answered. For whatever reason, it seems that using XGBoost with C++ in a DLL project requires additional includes above and beyond what is required for using it in a console application.
I am currently building the DLL project with the addition of:

QUESTION

Restrict child process access to shared memory and message queues

Asked 2017-Sep-06 at 16:47

I am writing a server that will accept untrusted Dynamic Library Modules (DLL,SO/DSO) loaded at runtime using Boost.DLL.

I would like to run the untrusted module in a separate process that only has access to the relevant shared memory (sometimes read only) and interprocess queues.

Boost does allow for a permissions object to be associated with the shared memory.

It seems like there might be a way to create a process on windows and Linux and then adjust the permissions.

How can a process be created that

has no permissions to start with (e.g. using AdjustTokenPrivileges on windows perhaps?), but
is then granted read access to shared memory mapped file (e.g. by setting permissions when constructing the shared memory segment?)

Or perhaps this is inherently too risky?

...

ANSWER

Answered 2017-Sep-06 at 16:47

First, from the docs:

Named resources offered by Boost.Interprocess must cope with platform-dependant permission issues also present when creating files. If a programmer wants to shared shared memory, memory mapped files or named synchronization mechanisms (mutexes, semaphores, etc...) between users, it's necessary to specify those permissions. Sadly, traditional UNIX and Windows permissions are very different and Boost.Interprocess does not try to standardize permissions, but does not ignore them.

All named resource creation functions take an optional permissions object that can be configured with platform-dependant permissions.

Beware, if you do so, then you immediately have to know about platform specific required permissiong:

Since each mechanism can be emulated through different mechanisms (a semaphore might be implement using mapped files or native semaphores) permissions types could vary when the implementation of a named resource changes (eg.: in Windows mutexes require synchronize permissions, but that's not the case of files). To avoid this, Boost.Interprocess [usually¹, red.] relies on file-like permissions, requiring file read-write-delete permissions to open named synchronization mechanisms (mutex, semaphores, etc.) and appropriate read or read-write-delete permissions for shared memory. This approach has two advantages: it's similar to the UNIX philosophy and the programmer does not need to know how the named resource is implemented.

¹ when not passing the permissions object

Your other question:

has no permissions to start with (e.g. using AdjustTokenPrivileges on windows perhaps?), but
is then granted read access to shared memory mapped file (e.g. by setting permissions when constructing the shared memory segment?)

No. The permissions object does not give permissions to the invoking process. The permissions object restricts access for other processes. I wager that as such, it only makes sense to specify permissions on create_only or open_or_create.

What I imagine is the usual route on Windows/Linux:

you start the server running as a specific user account
you start the clients using the same account
you create the IPC objects to be accessible only from the account that created them (the owner)

I wager that Windows will allow more fine-grained control due to its Access Control Lists (not tested this): they should allow you to specify additional/different accounts that have access.

On linux, it is highly likely that to achieve such control, additional system calls are necessary (e.g. to change the owner/group of the shared object and/or add such a group the client user account as primary/secondary group).

Summarizing: _I would focus on granting access to a specific recipient, instead of "starting a recipient without any permissions". The latter is impractical (processes might not even function "without any permissions") and elevating privileges during runtime is a lot more difficult than using statically assigned/administered permissions. Not to mention it's inherently less secure to add permissions on the fly.
