Where are you from? Which country?

France. I could try through proxies if it can help.

NinoNinov commented 7 months ago

Hello,

I have the same error message, when try to use ticker.info functionality. Even after the last update from 6 Dec (0.2.33) the issue still exisit. I am from Bulgaria and do not use VPN, could you give some info does it possible to fix the issues locally using VPN or other option.

bot-unit commented 7 months ago

@NinoNinov try, please:

pip uninstall yfinance
pip install yfinance --upgrade --no-cache-dir

and remove yfinance.cache if it exists

ValueRaider commented 7 months ago

and remove yfinance.cache if it exists

I prefer they keep cache and debug the error. What is the string?

Sounds easy to fix. #1084

yfinance

@NinoNinov it's error from old code. Try latest version

I tried to updated to last version several time but still the same issue, as you can see from my screenshot made several minutes ago. https://i.ibb.co/F4sgLj2/yfinance.jpg

bot-unit commented 7 months ago

@NinoNinov The latest version is 0.2.33, but you have installed 0.2.24

NinoNinov commented 7 months ago

@bot-unit many thanks for support! Now it is working, the issie was that I tried to update with comand: pip install yfinance which was working in the past but is not working now. Instead that used: pip install yfinance --upgrade --no-cache-dir amd now works. @dmoklaf try to fix issue with second command

dmoklaf commented 7 months ago

@NinoNinov I followed your reinstall procedure with the specific flags including --no-cache-dir and the bug is still there. I may have time in the next two weeks to dig into these typing issues. The fix seems simple (may be a one liner), what worries me is the other parts of the library that I really don't use and don't know, including the cache whose existence is new to me. And why am I the only one to see this.

bot-unit commented 7 months ago

@dmoklaf the caching is needed for cookies. Since Yahoo started blocking requests without crumbs, we should obtain cookies, then crumb, and only then make requests.

ValueRaider commented 7 months ago

@dmoklaf Give us the cookie cache database file, I want to understand how error happened. I've updated README to explain where file is.

dmoklaf commented 7 months ago

Here are the cache files. Let me know if I should perform another test with clean (reset) cache files. Even if small, I had to zip them as GitHub doesn't accept .db files Archive.zip

MacOS 14.2 Python 3.11.6 yfinance 0.2.33

ValueRaider commented 7 months ago

I understand the problem but no idea how it happened. 2023-11-21T11:32:20.866294 is in the database, using T to separate date from time instead of a space - this should be impossible because peewee handes everything. The T causes parse back into datetime to fail.

Branch hotfix/cookie-cache-date has a workaround, try it.

dmoklaf commented 7 months ago

Branch hotfix/cookie-cache-date has a workaround, try it.

It works ! Now that you have identified the culprit being the storage format in Sqlite, I can complete the missing pieces as I know this part well: 1- Sqlite has no true DATETIME storage. Even if the field type "seems" to exist, it's just for Sqlite an alias for a string storage. 2-The mapping from a Python datetime to the stored string is performed by the Python sqlite3 driver. I don't know if peewee relies on it or not but, based on the bug you elucidated, it seems it does replicate the same issue described below. 3-The sqlite3 driver offers (until Python 3.12, this will be removed in a future release) a default mapping that is the one you were expecting (with a space between the date and the time). 4-But I had in my dependencies tree a third-party library which enforces a strict ISO8601 mapping to make sure all stored dates can be parsed following the ISO norm in its own Sqlite database. The ISO norm uses a T between the date and the time

Note: the Python documentation is confusing because it states that its default mapping is ISO-compliant. But this is wrong. Using a space is not ISO compliant and is a tolerance stemming from RFC 3339, not supported by all tools. Strict ISO forbids the space, and requires a T.

The future for Python may favor strict ISO as the documentation announces default mappings will be removed, and offers as a compensation mapping examples strictly based on ISO (and not based on the RFC 3339 tolerance): https://docs.python.org/3/library/sqlite3.html#default-adapters-and-converters-deprecated https://docs.python.org/3/library/sqlite3.html#sqlite3-adapter-converter-recipes

So your workaround may be going in the right direction.

Given this is an edge case, I have lowered priority for merge into dev branch.

Hello @dmoklaf for the code below I receive again issue "404 Client Error: Not Found for url:" I use the same code with S&P 500 Data and everithing works fine, if I change nasdaq100[i] with nasdaq100[1], 2, 3 code is working. Do you have idea from where is comong that issue, I guess something with the list is not ok.

stock_data = PyTickerSymbols()
nasdaq100 = stock_data.get_stocks_by_index('NASDAQ 100')
nasdaq100 = pd.DataFrame(nasdaq100)
nasdaq100=nasdaq100['symbol'].tolist()
nasdaq100_len=len(nasdaq100)

list_stocks=[]
for i in range(0,nasdaq100_len):
    stock = yf.Ticker(nasdaq100[i])
    stock_i=stock.info
    stock_i=pd.DataFrame.from_dict(stock_i.items())
    stock_i.columns =['Name', 'Value'] 
    stock_i.rename(columns = {'Value':nasdaq100[i]}, inplace = True)
    list_stocks.append(stock_i)

S&P Code which is working

#Extracting actual companies in S&P 500 Index + calculating lenght of companies in the index
table=pd.read_html('https://en.wikipedia.org/wiki/List_of_S%26P_500_companies')
sp500 = table[0]
sp500 = sp500["Symbol"].tolist()
sp500_len = len(sp500)

#Table from which will merge coulumns into main table - adding more info about S&P 500
aditional_info_sp500=table[0]
aditional_info_sp500=aditional_info_sp500[["Symbol","Founded","GICS Sector","GICS Sub-Industry","Date added"]]

#For loop whcih to store data for S&P 500 companies from yfinance to DataFrame in Pandas 
#IT IS LOADING APPROXIMATELY 5 MINUTES
list_stocks=[]
for i in range(0,sp500_len):
    stock = yf.Ticker(sp500[i])
    stock_i=stock.info
    stock_i=pd.DataFrame.from_dict(stock_i.items())
    stock_i.columns =['Name', 'Value'] 
    stock_i.rename(columns = {'Value':sp500[i]}, inplace = True)
    list_stocks.append(stock_i)

@NinoNinov I could reproduce your error, and simplified the case to this:

import yfinance
yfinance.Ticker("ATVI").info

which raises a 404 error.

This error is coming from Yahoo and not from this library, as Yahoo declares ATVI (Activision) as a private company: https://finance.yahoo.com/company/activision-422a?h=eyJlIjoiYWN0aXZpc2lvbi00MjJhIiwibiI6IkFjdGl2aXNpb24ifQ==&.tsrc=fin-srch

So this is an unrelated error that is not in the scope of this project.

Many thanks, PyTickerSymbols is not up to date, will scrap NASDAQ data from web.
