Can you just change the Time column to pandas date-time dtype and then do the fit?That might avoid this error.Auto Vimal On Tuesday, September 5, 2023 at 08:01:54 AM EDT, EMOBS @.***> wrote:

Thank you for the quick reply!
I did that this way already: data['Time'] = pd.to_datetime(data['Time'], format='%Y.%m.%d %H:%M:%S')
Then I checked the data type of the 'Time' column after conversion which was of the datetime64[ns] type then.
However, the issue persists.
Ok then I would need you to do the following:Post a snippet of your data (100 rows) if possible in a zip file and attach it to this reply.Then post a code snippet of how you are calling Auto_TS. I can then find out what the problem is. Thanks for trying out Auto_TSAuto Vimal On Tuesday, September 5, 2023 at 08:24:09 AM EDT, EMOBS @.***> wrote:

Sure thanks, here's the dummy data.zip. And this is the python code initiating the model fit:
model = auto_timeseries(
score_type='rmse',
time_interval=Timeframe_frequency,
model_type='best',
verbose=2,
forecast_period=2,
non_seasonal_pdq=None,
seasonality=True
)
# Convert the 'Time' column to the desired string format
data['Time'] = pd.to_datetime(data['Time'], format='%Y.%m.%d %H:%M:%S')
model.fit(
traindata=data[:-2], # Excluding the last 2 rows for training
ts_column='Time',
target=target_col
)
Thanks for your support!
By the way, the csv file is read using data = pd.read_csv(file_path, encoding='utf-16', delimiter=';')
and stored into a pandas data frame and then passed as an argument (data
) to the function that creates the model and initiates the fit as in the code above.
Any news on this issue yet? We're you able to reproduce the error and/or pinpoint the cause? If you need more details, please let me know.. Thanks.
Hey I am not able to read your input_python.csv file - I tried every variation. I think this the problem.Can you fix it?datapath = '../../downloads/data/'filename = 'python_input.csv' dft = pd.read_csv(datapath+filename, encoding='utf-16', delimiter=';')print(dft.shape) dft.head(1)

I just tried: Downloaded it myself from this topic, unzipped and opened the file without problems. Shall I send you a copy by email?
Hello, I sent you 2 emails regarding this issue, but not sure if you read or even received those. Please let me know, thanks in advance.
Hello: I gave you the code snippet I used to read your zip file and your file did not come out correctly. Let me put it here again for you to try it and report back: See my screenshot of how badly the file comes out when you use this code.
dft = pd.read_csv(datapath+filename, encoding='utf-16', delimiter=';')print(dft.shape)
dft.head(1)```

Hi and thanks for your reply!
Using this code:
file_path = os.path.join(data_path, 'python_input.csv')
data = pd.read_csv(file_path, encoding='utf-16', delimiter=';')
logging.info(f"Data shape: {data.shape}")
logging.info(f"Data sample:\n{data.head()}")
I get this as the data shape and head after reading the file:
Data shape: (500, 21) Data sample: Time Data1 Data2 ... Data3 Data4 Data5 2023.09.07 22:10:00 1.06958 1.06947 ... 42.835099 18.564245 1.071799 2023.09.07 22:15:00 1.06948 1.06949 ... 35.744064 18.600451 1.071745 2023.09.07 22:20:00 1.06948 1.06953 ... 42.293215 20.935565 1.071687 2023.09.07 22:25:00 1.06954 1.06958 ... 41.152948 23.629927 1.071650 2023.09.07 22:30:00 1.06958 1.06954 ... 43.177273 22.100989 1.071612
Looks good to me. What do you think?
It might be a difference in pandas versions. I am getting a badly formed dataframe when I use the CSV file above using read_csv. See Screenshot below

This error is thrown when fit is initiated:
could not convert string to float
on the Time columns of my data. This column is of the datetime data type and there are no missing or incorrect values in it. What can be done to fix this?
