            Set slaves for jupyterq
            Asked 2019-Aug-13 at 07:08

            I am running Q in jupyter. To enable multiple slaves, jupyter requires to be run with parameter -s.

            How can I launch a kernel in jupyerq with slaves enabled? I tried passing '-s 20' into argv here in the runkernel.py, but the kernel wouldn't start at all

            You question is a bit difficult to understand but I guess you tried to check whether the user's answer is the same as the randomly picked value. If that's the case then this would do:

            Install qlib

            This quick start guide tries to demonstrate. Here is a quick demo shows how to install Qlib, and run LightGBM with qrun. But, please make sure you have already prepared the data following the instruction.
            It's very easy to build a complete Quant research workflow and try your ideas with Qlib.
            Though with public data and simple models, machine learning technologies work very well in practical Quant investment.
            This table demonstrates the supported Python version of Qlib: | | install with pip | install from source | plot | | ------------- |:---------------------:|:--------------------:|:----:| | Python 3.7 | :heavy_check_mark: | :heavy_check_mark: | :heavy_check_mark: | | Python 3.8 | :heavy_check_mark: | :heavy_check_mark: | :heavy_check_mark: | | Python 3.9 | :x: | :heavy_check_mark: | :x: |.
            Conda is suggested for managing your Python environment.
            Please pay attention that installing cython in Python 3.6 will raise some error when installing Qlib from source. If users use Python 3.6 on their machines, it is recommended to upgrade Python to version 3.7 or use conda's Python to install Qlib from source.
            For Python 3.9, Qlib supports running workflows such as training models, doing backtest and plot most of the related figures (those included in notebook). However, plotting for the model performance is not supported for now and we will fix this when the dependent packages are upgraded in the future.
            QlibRequires tables package, hdf5 in tables does not support python3.9.
            Users can easily install Qlib by pip according to the following command.
            Also, users can install the latest dev version Qlib by the source code according to the following steps:. Tips: If you fail to install Qlib or run the examples in your environment, comparing your steps and the CI workflow may help you find the problem.
            Before installing Qlib from source, users need to install some dependencies: pip install numpy pip install --upgrade cython
            Clone the repository and install Qlib as follows. git clone https://github.com/microsoft/qlib.git && cd qlib pip install . Note: You can install Qlib with python setup.py install as well. But it is not the recommanded approach. It will skip pip and cause obscure problems. For example, only the command pip install . can overwrite the stable version installed by pip install pyqlib, while the command python setup.py install can't.
