Check the values of train_new. You'll see that the columns mentionned are not of the expected types.
Another suggestion, i'm not sure of xgboost's handling of nulls. Might be that in those columns aswell.

August 20, 2020 - Created an xgboost model saved it in a pickle file and loading it to predict on a new dataset with the same features. Cannot perform prediction on the new data gives an error: AttributeError: 'DataFrame' object has no attribute 'feature_names'

Perform Label encoding for the features like Alley, Condition2, etc (mentioned in your error). For example:
train_new['Electrical'] = le.fit_transform(train_new['Electrical'].astype(str))
The above is the snippet for your reference. Do not apply .astype(str) for Condition2 only. Excluding that u need to apply the line that I gave u for all attributes (mentioned in error). I hope this solves your error.

Update from OP
I realised that tasks were only failing after I annotated some columns into obs - a tabular file (23). I thought one of the columns must be throwing things off so I cut that file into two and annotated each in and tried to do the next step - both failed.

df[col] will return a DataFrame object (not a Series) if df contains more than one column with the same name. Make sure you do not have more than one column with the same name in df as that is the likely source of this error.

You seem to somehow get back a DataFrame and not a Series by calling X[col]. Not sure why, because you did not supply the full structure and data of your dataframe.
.dtype is for pandas Series https://pandas.pydata.org/docs/reference/api/pandas.Series.dtype.html
.dtypes is for pandas Dataframes (and seems also to work with pandas Series) https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.dtypes.html

October 21, 2019 - The above call results in AttributeError: 'DataFrame' object has no attribute 'dtype' which is difficult to interpret. Under the hood the set logic tries to maintain dtype but the duplicate column label results in finding a DataFrame instead of a Series.

This works for me on the current version of pandas:
pd.to_datetime(df)
0 2015-02-04
1 2016-03-05
dtype: datetime64[ns]
Pandas to_datetime has special support to parse a datetime column from a supplied DataFrame input iff it contains specifically "year", "month" and "day" columns (order doesn't matter, and case sensitivity doesn't either).
It's likely you're working with a much older version of pandas in which case I'd recommend an upgrade!
However...
If upgrading isn't an option, you can always join the columns and call to_datetime on the Series.
Try joining the columns and then applying pd.to_datetime.
pd.to_datetime(df[['year', 'month', 'day']].astype(str).apply('-'.join, 1))
0 2015-02-04
1 2016-03-05
dtype: datetime64[ns]

I would recommend you start off by reading the 10min pandas Quick Guide . This should get you on the right track (at the very least you will be able to load data into pandas). Afterwards, you should also be able to tell why your current code doesn't make much sense.

Is there a column in your file called data? you already have a df from the first line. Maybe you just want to rename the columns. df.rename(columns={})
