What version of python are you using?
3.8.5 (default, Sep 3 2020, 21:29:08) [MSC v.1916 64 bit (AMD64)]
This seems to be caused by the self.session
initialized in the constructor not being close()
when the instance of _YahooFinance
in base.py
is destroyed.
For example, instead of retrieving multiple tickers in a list at once, it occurs when you create a method that processes them one by one in a loop.
def get_info_of_specified_ticker(ticker):
result_data = {}
tickerinfo = Ticker(ticker)
summary = tickerinfo.summary_detail[ticker]
# Process to extract only desired information to result_data
return result_data #### At this point the warning in the title occurs
What the user can do is to explicitly close() the session before the instance is destroyed.
# Process to extract only desired information to result_data
tickerinfo.session.close() #### Explicitly close() the session
return result_data
Essentially, add a destructor to the _YahooFinance
class in base.py
and close()
self.session
in it. If you have other resources to deal with in your destructor, you should add those as well.
hi all, I am new at python programming. I just try to get data using history function and there is no problem if I dont use thread. If I try to use thread I get following errors.
"ResourceWarning: unclosed <ssl.SSLSocket fd=5084, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, .....>"
"Exception ignored in: <ssl.SSLSocket fd=5264, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, ...."
these errors/warnings dont effect my program but it is annoying to see a lot of unwanted text at console.
I try to get rid of these warnings by using warnings.simplefilter("ignore", ResourceWarning) statement but it is useless.
I am not sure is this a important issue but any help about this topic appreciated
