Startup problems

[roylend]

Hello Scott,

I like this project a lot but I have issues getting it up and running. I tried both under Windows and Ubuntu. In Ubuntu at least the pip3 install alphapy worked fine.

But when I move to one of the example directories and try to run the commands you show in the documentation, it just does not find the alphapy or market_flow files. Even when I put those files inside the same directory and try to run them from the Python editor environment, I get all kinds of errors.

How can you run the examples directly from the Python editor environment?

Could you post some error logs here? Thanks.

Hello Mark,

My first issue was with pandas. It appears the library is very reliant on having the right version of Pandas (not the last one). I managed to solve this one by trying all Pandas versions between 1.19 and 2.22. When using 2.22 it worked.

The issue I now have is with installing tkinter within the Ubuntu environment. When I run marketflow, I get this tkinter issue. However, when I try to install tkinter for Python3, I get 404 errors from the Ubuntu archive.

Let’s hope I manage to solve these installation issues. One question about the library itself. I recently saw from academic research that AI models trained on Japanese stocks for example performed equally well on US stocks as compared to AI models trained on US stocks. So can I use Alphapy to train the algorithm on let’s say the history of 500 stocks and then use this complete trained model to predict on all invididual stocks? Instead of training only on the history of the specific stock you are trying to predict?

Mark,

Managed to fix the tkinter issue as well by updating the URL’s for the Ubuntu environment to “old-releases”.

Now when I run marketflow or “main” in the directory with the Trading example. I get the following error: None Exception “unhandled RuntimeError” Context has already been set File:/ /usr/lib/python3.5/multiprocessing/context.py, Line: 231

So I encapsulated this mp.set_start_method(‘forkserver’) into a Try / except RunTimeError: phrase

Then Marketflow runs until a window pops up called “Client Forking” where I can choose with parent and child process. With both choices the running seems to be stop.

So the whole multi-thread process seems to be an issue somehow.

I managed to completely run the example by commenting out two areas which generated bugs in Python3.5 in Ubuntu:

· Plot_learning_curve in plots.py

· Recursive feature elimation part in main.py

Yes, the multithreading issue has been ongoing because of the njobs > 1 issues with xgboost, Keras, etc. I apologize for the examples not working; the package dependencies have been constantly breaking the code, specifically sklearn and pandas deprecations and API changes.

Mark,

I still any way to have multi-class classification modeled as well? I did notice two-class classification and regression in the two trading related examples but could not find how to use it in a multi-class environment.

Mark, we will be looking to also build an integration with Interactive Brokers API on top of this going forward? Has something like this already been build?

Backend threading problems have been resolved.
