It had been working all the time before today. I don't know why it doesn't work today.
import yfinance as yf
df = yf.Ticker('MMM').history(start='2021-01-01',end='2021-07-10')
File "D:\anaconda3\envs\tensorflow\lib\site-packages\yfinance\base.py", line 157, in history
data = data.json()
File "D:\anaconda3\envs\tensorflow\lib\site-packages\requests\models.py", line 900, in json
return complexjson.loads(self.text, **kwargs)
File "D:\anaconda3\envs\tensorflow\lib\json\__init__.py", line 357, in loads
return _default_decoder.decode(s)
File "D:\anaconda3\envs\tensorflow\lib\json\decoder.py", line 337, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "D:\anaconda3\envs\tensorflow\lib\json\decoder.py", line 355, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
I upgraded to the latest version and the problem was solved. Installation code for latest version: pip install yfinance==0.1.62
If Anyone Still facing problem with jsonDecoder error. Try deleting yfin from venv of pycharm folder. Somehow my system was not upgrading yfin in venv of pycharm. I had to manually delete yfin folder and upgrad yfin. Its now working for me. Thanks https://stackoverflow.com/a/68601710/16442394
The Below patch fixed my issue: In /usr/local/lib/python3.8/dist-packages/yfinance/base.py Make below changes:
# Getting data from json
num_tries = 4
url = "{}/v8/finance/chart/{}".format(self._base_url, self.ticker)
while num_tries > 0:
data = self.session.get(
url=url,
params=params,
proxies=proxy,
headers=utils.user_agent_headers
)
if "Will be right back" in data.text:
raise RuntimeError("*** YAHOO! FINANCE IS CURRENTLY DOWN! ***\n"
"Our engineers are working quickly to resolve "
"the issue. Thank you for your patience.")
if data.status_code == 404:
_time.sleep(0.5)
num_tries -= 1
continue
else:
data = data.json()
break
if num_tries == 0:
print("%s failed to get information"%self.ticker)
data = {}
