possibility using this library from IronPython

[xyont]

hi,

an interesting library to use, i'm trying but not succeed in solving steps.

some error messages shown,
IOError: [Errno 2] Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=4.0.4.1, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

any hints or suggestion?

regards,

Hi,
Not sure, but actually this library do not need C# unsafe memory access.
It is interesting that line 30 of your code throws the error, which means there is only problem with Model.Solve() method.
Can you please also check the Model.Solve_MPC() method too?

indeed, all model definition is work except in model.Solve(). I guessed this problem's related to CSparse.dll and System.Memory.dll incompatibilities. Where's another source to download of both DLL's file instead from NuGet?

also, i'm checking with model.Solve_MPC() but the problem persists.

**edited
previously i'm missing some DLL and trying to repair by add, however another problem in CSparse.dll and shown error message as:

SystemError: Method 'Solve' in type 'CSparse.Double.Factorization.DenseLU' from assembly 'BriefFiniteElementNet.Common, Version=2.0.5.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

thanks in advance,

Could you please check and tell me the version of CSparse.dll which you are referencing in the code (line 3)?
you should use V3.5 (here is nuget). because the later version after 3.5 are not compatible with dotnet4.5 (they are dotnet 4.6 and later) BFE stuck with Csparse V 3.5 in order to be compatible with net45

many thanks for the hints about CSparse.dll incompatibilities, i do roll-back to previous version as suggested and it seems to be working now.

i'll try to use the library from IronPython and reporting when still have any issues.

@xyont could we please continue this conversation in issue #165 ?
Thanks
