Hi there, My application has suddenly started to throw this error? It is a Python 3.4 application hosted in Flask 3.4

The error is thrown by one of the packages in "dist-packages", to which I do not have access to check. Has anyone seen this error earlier? Below is the stack trace. Any guidance will be helpful.

I can see that I get this error when I try to use scikit learn (SVM) library. I have not explicitly installed this library in my installation? Do I need to or PythonAnywhere has a global package directory from where it can be resolved?

Also where is the "dist-packages" folder. I cannot see it, I guess this is PythonAnywhere's global package directory. I may be entirely wrong. Please correct me.

This is solved now

After some fiddling I found, it was the print function. print cannot handle numpy array.. you need to convert to str first.

Thanks for your attention.

glad you figured it out! :)
