Reshape error when using mutual_info regression for feature selection - python

I am trying to do some feature selection using mutual_info_regression with SelectKBest wrapper. However I keep running into an error indicating that my list of features needs to be reshaped into a 2D array, not quite sure why I keep getting this message-
#feature selection before linear regression benchmark test
import sklearn
from sklearn.feature_selection import mutual_info_regression, SelectKBest
features = list(housing_data[housing_data.columns.difference(['sale_price'])])
target = 'sale_price'
new = SelectKBest(mutual_info_regression, k=20).fit_transform(features, target)
This is my traceback:

The transformer expects a 2D array, of shape (n x m) where n is the number of samples and m the number of features and if you look at the shape of features I imagine it will display: (m,).
Reshaping arrays
In general for a feature array of shape (n,), you can do as the error code suggests and call .reshape(-1,1) on your feature array, the -1 lets it infer the additional dimension: The shape of the array will be (n,m), where for a 1 feature case m = 1.
Sklearn transformers
The above being said, I think there is additional errors with your code and understanding.
I would print features to screen and check it is what you want, it looks like you are printing a list of all the column names except sale_price.
I am not familiar with SelectKBest but it requires an (n,m) feature array not a list of column names of the features.
Additionally, target should not be the name of the target column, but an array of shape (n,), where its values are the observed target values of the training instances.
I would suggest checking the documentation (previously referenced) while you are writing your code to make sure you are using the correct arguments and utilising the function as it is intended.
Extracting features
Your data seems in a strange format (dictionary's nested in a pandas DF). However is a explicit example of how I would extract features from a pd.DataFrame for use with functions from the SKlearn framework.
housing_data = pd.DataFrame({'age': [1,5,1,10], 'size':[0,1,2,0],
'price':[190,100,50,100]
})
feature_arr = housing_data.drop('price', axis=1).values
target_values = housing_data['price']
Print feature_arr and you will hopefully see your issue. Normally you would then have to preprocess the data to, for example, drop NaN values or perform feature scaling.

Here is the code I am using:
df['C'] = np.where((df['spread'] > 60) & (df['volume'] > df['Ma_mult_high']),'green','red')
fig = go.Figure()
# add OHLC trace
fig.add_trace(go.Candlestick(x=df.index,
open=df['open'],
high=df['high'],
low=df['low'],
close=df['close'],
showlegend=False))
# add moving average traces
fig.add_trace(go.Scatter(x=df.index,
y=df['ma'],
opacity=0.7,
line=dict(color='blue', width=2),
name='MA 5'))
fig.add_trace(go.Scatter(
x = df.index,
y = df['close'],
mode = 'markers',
marker_color=df.C
))
fig.update_layout(xaxis_rangeslider_visible=False).show()`
the output
in the image, you can see that plot both True and false signal, maybe because the marker_color = "C" but if change that and use only color names it will plot noting even if i change the y = df['close'], i get the same problem

It seems to me that the issue is in your np.where() statement, likely with the nan values in Ma_multi_high producing the false statement in df['volume'] > df['Ma_mult_high'] that result in 'red'.
Try this:
df['C'] = np.where((df['spread'] > 60) & (df['volume'] > df['Ma_mult_high'].fillna(0)),'green','red')

I wonder how can we fill the NaNs from all columns of a dataframe, except some.
For example, I have a dataframe with 20 columns, I want to fill the NaN for all except two columns (in my case, NaN are replaced by the mean).
df = df.drop(['col1','col2], 1).fillna(df.mean())
I tried this, but I don't think it's the best way to achieve this (also, i want to avoid the inplace=true arg).
Thank's

You can select which columns to use fillna on. Assuming you have 20 columns and you want to fill all of them except 'col1' and 'col2' you can create a list with the ones you want to fill:
f = [c for c in df.columns if c not in ['col1','col2']]
df[f] = df[f].fillna(df[f].mean())
print(df)
col1 col2 col3 col4 ... col17 col18 col19 col20
0 1.0 1.0 1.000000 1.0 ... 1.000000 1 1.000000 1
1 NaN NaN 2.666667 2.0 ... 2.000000 2 2.000000 2
2 NaN 3.0 3.000000 1.5 ... 2.333333 3 2.333333 3
3 4.0 4.0 4.000000 1.5 ... 4.000000 4 4.000000 4
(2.66666) was the mean

fig = px.scatter_geo(df, locations="country", color = "country",
projection="natural earth")
fig.show()
On the output side, I am able to get the world map and in the legends, all the countries do appear. The problem is the countries are not shown on the map.

The data did not contain the three-digit country codes. When the data was merged with another dataset having three-digit country codes, the required output was obtained.

I have a df where every row looks something like this:
series = pd.Series({0: 1.0,
1: 1.0,
10: nan,
11: nan,
2: 1.0,
3: 1.0,
4: nan,
5: nan,
6: nan,
7: nan,
8: nan,
9: nan,
'B': 3.0,
'D': 1.0})
For every value in D I want series[series.D] to be 2 and, all numerical values that are higher than series.D, also to be 2. It's kinda like a 'forward replace'.
So what I want is:
target = pd.Series({0: 1.0,
1: 2.0,
10: nan,
11: nan,
2: 2.0,
3: 2.0,
4: nan,
5: nan,
6: nan,
7: nan,
8: nan,
9: nan,
'B': 3.0,
'D': 1.0})
So far I've got:
def forward_replace(series):
if pd.notnull(series['D']):
cols = [0,1,2,3,4,5,6,7,8,9,10,11]
target_cols = [x for x in cols if x > series.D]
series.loc[target_cols].replace({1:2}, inplace=True)
return series
It seems like it's not possible to use label based indexing with numerical column labels?
