            Manually/locally installed python packages dont show up in visual studio
            Asked 2021-Apr-16 at 07:38

            So I manually installed a locally downloaded python package by going into the folder directory and using the cmd command:

            python setup.py install

            After that it just installed itself normally. Using the python function help("modules") in cmd also confirmed that it was installed correctly as I can see the name being given out. The two modules are called binance_d and binance_f

            I followed this document and I can get what I want. The most importance thing is that the command does not copy the generated files into the pyhton 3.9.4 folder automatically. You have to copy them manually.

            1) first download the project under this link and then unpack the file.

            It's because of version compatibility, you should either downgrade your Python-socketIo version to 3 which works with SocketIo version 1 in Js, or upgrade your Js client SocketIo version to 3 which works with Python-SocketIo 5.

            recommender systems: Convert UUIDs to 32 bit ints for recommender libraries
            Asked 2018-Jan-02 at 21:53

            LightFM and other libraries ask for a 32 bit integer id e.g for users. But, our user id is a UUID e.g. 0003374a-a35c-46ed-96d2-0ea32b753199. I was wondering what you would recommend in scenarios like these. What I have come up with is:

            • Create a bidirectional dictionary either in memory or in a database to keep a UUID <-> Int mapping. e.g. https://github.com/jab/bidict
            • Use a non cryptographic hash function like MurmurHash3 or xxHash. For e.g. for 10 million UUIDs, I got around 11,521 or 0.1% collision using xxhash. Is that negligible for a recommender system?

            I'm also curious on how this would apply in an online prediction scenario, where given the UUID, user interactions and the model, I have to predict the recommendations for a model which needs 32 bit integers. If I use the in memory bidict approach, then that won't work in this case and hence I may have to create a persistent key-value store in the worst case.

            ...

            ANSWER

            1. This will definitely work, and is probably the solution the vast majority of users will choose. The disadvantage lies, of course, in having to maintain the mapping.
            2. A hashing function will also work. There are, in fact, approaches which use hashing to reduce the dimensionality of the embedding layers required. One thing worth bearing in mind is that the resulting hash range should be relatively compact: most implementations will allocate parameters for all possible values, so a hashing function that can hash to very large values will require exorbitant amounts of memory. Hashing following by a modulo function could work well; the trade-off then is between memory required to hold all parameters and collision probability.

            In LightFM as well as most other implementations, recommendations can only be made for users and items (or at least for user and item features) that were present during the training. The mapping will then be a part of the model itself, and be effectively frozen until a new model is trained.
