Dear all,
I am trying to solve an optimization problem from jupyter notebook using `JuMP` with solver `Ipopt` (`Pardiso` linear solver). I can solve the problem without any problem when the code is in a `filename.jl` file and I run it using `include("filename.jl")` method. However, when I am trying to run the same code line by line from the jupyter notebook, I get the following errors:
1. While running the codeblock:
```julia
Libdl.dlopen("/usr/lib/x86_64-linux-gnu/libomp.so.5", RTLD_GLOBAL)
```
(_the path name is correct, it does contain the file and so on_)
I get the error:
```julia
LoadError: could not load library "/usr/lib/x86_64-linux-gnu/libomp.so.5"
/usr/lib/x86_64-linux-gnu/libomp.so.5/libomp.so.5: cannot open shared object file: No such file or directory
```
1. While running the codeblock
```julia
set_optimizer_attribute(model, "linear_solver", "pardiso")
```
I get the error:
```julia
Exception of type: DYNAMIC_LIBRARY_FAILURE in file "Common/IpLibraryLoader.cpp" at line 67:
Exception message: libpardiso.so: cannot open shared object file: No such file or directory
```
I am not sure what is going on. Any tips/suggestion will be much appreciated.

I’m not sure then. It’s likely that Jupyter is messing with your load path. This seems more like a Jupyter question than one specific to Ipopt.

Yes, I think so too as well. I was trying to run this on `MIT Supercloud`’s jupyter environment and found that it does not have the same environment variables as their terminal system. I have asked the people in charge of `MIT Supercloud` to help with this. I am closing this issue, thanks @odow !

Okay, yeah if this is on MIT’s cloud environment any number of things could be set up differently.
If you can’t figure out the problem, you should be able to compile a new version of Ipopt with Pardiso included, and then use an override:

Thanks @odow ! Sounds good, the supercloud admins have given me some tips, let me try to implement those and see if I can make it work. If not, I will try to compile a new version of Ipopt as you suggested.
