ValueError: datetime64/timedelta64 values and dtype must have a unit specified

I'm getting the below behavior when calling get_news_headlines in the python api. I'm running python 3.10.7, and eikon version 1.1.16, windows 11 Pro

Input:

> import eikon as ek
> ek.get_news_headlines('ORDER IMBALANCE', date_from='2022-10-19T00:00:00', date_to='2022-10-19T23:59:59', count=100)

Error:

The error is dependent on the data being returned. I do not get this error for headline searches with a different query. Any ideas?

Hello @drdan ,

I was not able to reproduce the issue in my local environment or CodeBook, with the same request, at this time, as expect not much time has passed so the result should be close.

It seems from the error that it does not originate with eikon library, rather with one of the eikon dependencies, suspecting numpy or pandas.

Would suggest to verify the versions of pandas and numpy against CodeBook versions:

and if found different, try upgrading to these.

Please let us know how this works on your side?

Hi, I am getting the same error code.

Using the below as an example, I believe the error only happens when no headlines were published during the time period specified in the search.

ek.get_news_headlines(query = 'Topic:RTRS Language:LEN ', date_from = '10-Sep-2022 01:00:00',  date_to = '10-Sep-2022 01:50:00', count = 100)

This is new. I just went back to some old code that used to work fine.

I am currently using:

Eikon version 1.1.16

Pandas version 1.5.1

Python 3.10.7

Unfortunately I can't say what versions I was using when the code last ran okay.

Hi @noel.randewich01 ,

I'm sorry to hear that you're facing an issue. However, I was not able to reproduce the issue in my local environment or CodeBook, with the same request.

Would suggest verifying the versions of pandas and NumPy against CodeBook versions as mentioned by Zoya in the previous comment

To be of help, below are the current version of the libraries you mentioned in the Codebook app

  • Eikon version 1.1.14
  • Pandas version 1.3.5
  • NumPy version 1.22.4
  • Python 3.8.13
