AttributeError: 'identity_trans' object has no attribute 'dataspace_is_numerical'

I am trying to create a histogram using ggplot, this is my code:

data = pd.read_csv('Weather_not_tidy.csv')
data = data.rename(columns={'Temp2009': '2009', 'Temp2010': '2010'})

tidyData = pd.melt(data2, value_vars=['2009', "2010"], id_vars=['month', 'day', 'hour_of_day'],
                   var_name='year', value_name='temperature')
tidyData

 month day hour_of_day  year  temperature
0   Jan 1   12  2009    -0.9
1   Jan 2   12  2009    -2.2
2   Jan 3   12  2009    4.2
3   Jan 4   12  2009    -4.7
4   Jan 5   12  2009    -7.8
... ... ... ... ... ...
725 Dec 27  12  2010    -6.8
726 Dec 28  12  2010    -11.0
727 Dec 29  12  2010    -10.6
728 Dec 30  12  2010    -3.0
729 Dec 31  12  2010    -2.7
730 rows × 5 columns

plot = (
    ggplot(tidyData, aes(x='temperature', fill='year'))
    + geom_histogram(data=tidyData.loc[tidyData['year']=='2009'], alpha=0.6, bins=10)
)
plot

and I keep getting this error:

AttributeError: 'identity_trans' object has no attribute 'dataspace_is_numerical'

I have access to a correct solution to this exercise and it still gives me the exact same error! I am using vscode on Ubuntu, Python 3.11.10 and am using a conda environment with the following dependencies:

name: MVE080
dependencies:
  - python=3.11
  - plotnine=0.12
  - numpy=1.26
  - pandas=2.1
  - pip=23.1
  - pip:
    - geopandas

I was expecting to see a histogram with temperature from -10 to 10 on the x axis and the count on the y axis! :(

I don't think you posted enough info to solve this problem, but that error means that somewhere in the code there is something called identity_trans and that somewhere in the code you are trying to access an attribute of that object that is not an attribute of that object.

I would look for identity_trans in the code and see where it's trying to reference dataspace_is_numerical as a start.

You posted some of your code but you need to show the part of the code that has dataspace_is_numerical in it for us to really help you.

Edit based on the log I think the problem is probably with pretty.py which is not your program but something that you installed to run with your program I think, perhaps reinstalling that could help.
