Unable to load shared library 'python37' or one of its dependencies

I am quite new to dotnet and Keras.NET, and I was trying to set it up on a goorm.io container. After installing the prerequisites (adding $HOME/.keras/keras.json for Tensorflow backend and pip install numpy), and then adding Keras.NET, I tried to run the XOR sample code, but ran into an error.
Unhandled exception. System.DllNotFoundException: Unable to load shared library 'python37' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libpython37: cannot open shared object file: No such file or directory

I do not know how to share with the python37 directory. If someone could direct me in the right direction, it would be much appreciated. By the way, I am using Linux if that helps.
Thanks

FluentNHibernate exception - Could not compile the mapping document

Before posting this question I reviewed:
Runtime error when trying to run Fluent NHibernate tutorial example
Fluent nHibernate error - Could not compile the mapping document: (XmlDocument)
and many more similar questions which I was hoping could shed some light on my issue. No luck so far:
I was working a solution for some time now and everything was going fine until my most recent change. The solution still compiles but fails on startup with this exception:
An unhandled exception of type
'FluentNHibernate.Cfg.FluentConfigurationException' occurred in
xx.Initialization.dll
in View Details it says:
An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail."
PotentialReasons: Count = 0
InnerException: Could not compile the mapping document: xx.Website.Persistence.Repository.Mappings.UI.yyDataDto.hbm.xml
Inner exception: JIT Compiler encountered an internal limitation.
The .hbm.xml file that the exception is referring to is intact and there were no changed made to it. All of my code changes are covered by tests and whatever I changed doesn't seem to involve the exception directly.
To troubleshoot this, I committed and pushed all of my changes (feature branch) and asked my co-worker to get latest version. He was able to run the solution without any exceptions. I tried restarting my VS2013, my workstation, deleting my repository and getting the solution from scratch through source control as well as by a direct copy of my co-worker's solution folder (latest version) and still receiving the same error.
Not sure what else to try. Any tips/suggestions would be greatly appreciated. Thanks!
edit/update:
Today I attempted to repair my VS2013 installation, that didn't help. I then updated to latest service pack 4. Also no results.
I'm guessing at this point that something may be wrong with my debugger/settings because if I build the project and launch it (without debugging or by navigating to Bin folder and executing directly) it runs without exceptions. If I debug, I get the exception.
Here's the stacktrace:

The solution was to uninstall VS2013 completely and re-install it from scratch. After I did that, the exception went away.
I tried to remember what could've caused this and so far my only suspicion is that maybe when I ran CCleaner (prior to this issue appearing), it removed files or registry entries which made VS behave in such a way.

Unexpected error while compiling project 'My.Web'
Exception has been thrown by the target of an invocation.
MSB0001: Internal MSBuild Error: refCount should not be less than 1.

I ran into the same problem in a similar environment. In my case, the project had a COM reference to the Active DS Type Library, which wasn't installed on the build server.
To fix the problem, I dropped the COM reference and added a reference to an interop assembly, which was then deployed to the build server.

Found the solution: instead of using <solution> in the build target I called msbuild directly with <exec>. Everything works now.

My problem it's similar with you, I'm have to eliminate two projects that relationship with my solution in mobil enviroment, that cause the conflict with the others projects in my solution.
My other projects are desktop, mvc, webapi enviroment.
I have to create a new solution for my others mobil projects

Using Images and Icons in WPF

I am trying to use an Icon in my WPF application, and some images for other things, but I keep getting errors from the Designer View saying stuff like "path-x is not a valid resource or cannot be found." - where "path-x" is the path of whatever image I am trying to use.
If it were looking in the right place, I bet it'd find it ;)
BUT, then, it decided to not give me that error anymore. So, I went ahead and clicked Run (F5), to see my new Icon in the title bar. Only to be confronted with this beast:
"System.Windows.Markup.XamlParseException

Updates
Here is the XAML that was produced for the icon when I tried to add the Icon using the Properties Pane:
<Fluent:RibbonWindow x:Class="One_Stop_Management.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:Fluent="clr-namespace:Fluent;assembly=Fluent"
Title="One Stop Management" Height="727" Width="1208" Icon="Resources\favicon.ico">
Latest Update
I can't even add an icon using the properties pane, below is the error it gives me.

Make sure the target is a resource. Then do something like this:
Icon="/MobilWPF;component/Resources/Images/MobileIcon.ico"
where MobilWPF is your namespace, or maybe you're project name? I forget my project name and my namespace are the same.

I've discovered that VS2008 sometimes causes problems like this when you add new resources and then rebuild the project. I've found if you clean the build and then rebuild from scratch the problem disappears. Looks like a VS2008 bug to me.

I fixed this same issue by setting these properties for the image:
Build Action = Content
Copy to Output Directory = Copy always

The exception, if you read through it, says the same thing:
InnerException: System.IO.IOException Message=Cannot locate resource 'images/favicon.ico'.
This is probably because the Images/favicon.ico icon image is not setup correctly. Make sure that it's Build Action is set to "Resource", and that it's in the project under the "Images" folder.

The answer seems to depend on where/how you store the icon. I was trying to do something similar to #iterationx's answer but it didn't work for me, and this is what I finished up with. I'm using VS 2010.
I added the icon as a resource via the project's properties page, under Resources, Add Resource (dropdown), Add existing file. Then I just used the file name in the Icon property:
Icon="my_icon.ico"

I recall a similar situation where my application was crashing, and I eventually tracked it down to an .ico error.
If you're using icons and Windows XP, XP does not support the 256x256 icons. You may need to open the icon in an editor, such as IcoFx, and delete the 256x256 icon.

Setting BuildAction to Resource in resource Properties solved this problem.
Greets

I'm sorry I can't be more helpful. On reading your question at first I thought it'd be just a type mismatch, like where you were specifying a string when it was meant to be an image. The issue seems to be one that has multiple possible resolutions. Instead of listing them all I'll just link you to the Microsoft Connect page that has them on it.

I had this same problem and found that if your project has a space in the name, it won't read the image files correctly. Hope that helps.

use Icon=".\Images\test.ico" this got me working
