            Answered 2021-Jun-07 at 23:24

            TPOT can take quite a long time depending on the dataset you have. You have to consider what TPOT is doing: TPOT is evaluating thousands of analysis pipelines and fitting thousands of ML models on your dataset in the background, and if you have a large dataset, then all that fitting can take a long time--especially if you're running it on a less powerful computer.

            If you'd like faster results, you have a few options:

            1. Use the "TPOT light" configuration, which uses simpler models and will run faster.

            2. Set the n_jobs parameter to -1 or a number greater than 1, which will allow TPOT to evaluate pipelines in parallel. -1 will use all of the available cores and speed things up significantly if you have a multicore machine.

            3. Subsample the data using the subsample parameter. The default is 1.0, corresponding to using 100% of your training data. You can subsample to lower percentages of the data and TPOT will run faster.

            Answered 2021-May-20 at 14:28

            make_union just unions multiple datasets, and FunctionTransformer(copy) duplicates all the columns. So the nested make_union and FunctionTransformer(copy) makes several copies of each feature. That seems very odd, except that with ExtraTreesClassifier it will have an effect of "bootstrapping" the feature selections. See also Issue 581 for an explanation for why these are generated in the first place; basically, adding copies is useful in stacking ensembles, and the genetic algorithm used by TPOT means it needs to generate those first before exploring such ensembles. There it is recommended that doing more iterations of the genetic algorithm may clean up such artifacts.

            After that things are straightforward, I guess: you perform a univariate feature selection, and fit an extra-random trees classifier.

            Does the "tpot" model object automatically apply any scaling or other transformations when .score or .predict is called on new out-of-sample data?

            That depends on the final pipeline that TPOT chose. However, if the final pipeline that TPOT chose has any sort of data scaling or transformation, then it correctly applies those scaling and transformation operations in the predict and score functions as well.

            The reason for this is because, under the hood, TPOT is optimizing scikit-learn Pipeline objects.

            That said, if there are specific transformations to your data that you want to guarantee happen with your data, then you have a couple options:

            1. You can split your data into training and test, learn the transformation (e.g., StandardScaler) on the training set, then also apply it to your test set. You would do both of these operations before ever passing the data to TPOT.

            2. You can make use of TPOT's template functionality, which allows you to specify constraints on what the analysis pipeline should look like.

            Still new to python and coding, only about 6 weeks into this adventure. I started a finance project to try and figure out what % of the portfolio should be in cash, and how much should be invested based on the current market performance.

            I didn't understand the question, I think you assume familiarity with some concepts here. If you can phrase your question more simply and shortly it would help me help you. Then again it might be only my inability.

            I will try to give you my 2 cents, according to what you I can understand from the post.

            First of all, I would like to point out that the way you initialized your lists is not optimal. Numpy has two very important functions:

            1. np.linspace: https://numpy.org/doc/stable/reference/generated/numpy.linspace.html

            2. np.arange: https://numpy.org/doc/stable/reference/generated/numpy.arange.html

            So for example, you should replace your options_market_status initialization with the simple one-liner numpy call: np.arange(0.5, -0.02, -0.01).

            Now, if I understand your main question, it is how to iterate over options_market_status and options_cash_req, such that the element from options_market_status is bigger or equal to the options_cash_req option, right? Since they have the same values in your question, I will give a general solution. If we are given an array a, and want to iterate over it in a nested loop, one solution can be:

            I've got some experience with rasterio, but I am not nearly a master with it. If I remember correctly, rasterio requires you to have installed the program GDAL(both binaries and python utilities), and some other dependencies listed on the PyPi page. I don't use conda at the moment, I like to use the regular python 3.8 installer with pip. Given what I'm seeing with your installation, I would uninstall rasterio and follow a different installation procedure.

            I follow the instructions listed here: https://rasterio.readthedocs.io/en/latest/installation.html
            This page also has separate instructions for those using Anaconda.

            The GDAL installation is by far the most annoying but once it's done, the hard part is over. The python utilities for both rasterio and gdal can be found here:
            https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal
            The second link is also provided on the PyPi page but I like to keep it bookmarked because there's a lot of good resources there!
