kandi X-RAY | pyx Summary

pyx is a Python library typically used in Web Site, Business applications. pyx has no bugs, it has no vulnerabilities, it has build file available and it has high support. You can download it from GitHub.

PYX is a flexible program that simulates the trading of equity using different algorithms. The algorithm currently being used is a mean reversion strategy. PYX buys and sells shares of stock based on the price compared to its upper and lower bollinger bands. How does it work?. Mean reversion is the theory suggesting that prices and returns eventually move back toward the mean or average. This mean that PYX utilizes is called a 50 day exponential moving average. PYX relies on two main dependencies, yahoo_finance and sqlalchemy. PYX also utilizes Python 3.5's built in datetime module.

pd.to_datetime(self.data['Date']) is not modifying self.data['Date'], you're throwing the result away, so when you reach in_range one of the arguments is still a string.

Change it to self.data['Date'] = pd.to_datetime(self.data['Date']).

It seems your X is pandas.DataFrame and in DataFrame code X[0] searchs column with name 0 but X doesn't have it.

If you want to get row with number 0 then you may need X.iloc[0]

Cython: Error in math expression (works fine in Python)

Asked 2021-Jun-12 at 08:42

I am trying to cythonize my Python code to improve performance.

I didn't make any change to my original python code, I just run the setup.py and get the .c files.

Now I have this issue: when I perform a basic math operation in Python, it works fine, while in Cython it doesn't work as expected.

The code snippet is the following, here I try to calculate the y-coordinate of a given x on a circle of center [3,0] and radius 1:

I suspect that cdivision=True is enabled inside your setup.py. In C, the division of two integer literals cuts off all decimal places. Consequently, the 1/2 inside your return statement equals 0.0. Instead, simply use floating-point literals, i.e.

MemoryError with FastApi and SpaCy

Asked 2021-Jun-12 at 06:42

I am running a FastAPI (v0.63.0) web app that uses SpaCy (v3.0.5) for tokenizing input texts. After the web service has been running for a while, the total memory usage grows too big, and SpaCy throws MemoryErrors, results in 500 errors of the web service.

...

ANSWER

Answered 2021-Jun-12 at 06:42

The SpaCy tokenizer seems to cache each token in a map internally. Consequently, each new token increases the size of that map. Over time, more and more new tokens inevitably occur (although with decreasing speed, following Zipf's law). At some point, after having processed large numbers of texts, the token map will thus outgrow the available memory. With a large amount of available memory, of course this can be delayed for a very long time.

The solution I have chosen is to store the SpaCy model in a TTLCache and to reload it every hour, emptying the token map. This adds some extra computational cost for reloading the SpaCy model from, but that is almost negligible.

Module not found error when importing a Cython .pyd file

Asked 2021-Jun-09 at 07:33

I know this might seem like a duplicated question, but I really could not find what I'm doing wrong... I wrote a .pyx file in order to compile it into a .pyd with cython. Long story short, it compiles my file just fine and creates a .pyd file. However, when I try to import that .pyd file I get an error saying No module named: "name_of_module". Note that this is my first time trying cython...

I am using venv with python3.9 on windows 10. I have cython installed along with minGW. To compile it into the .pyd file, I imply type in the command prompt in the same directory as the .pyx file:

python setup.py build_ext --inplace
