fit function expected 2D array, got 1D array instead

I am using Linear Regression to predict the 'Value' throughout the years, I have the following data, i imported from a csv file : **df.head()** :

LOCATION    INDICATOR   SUBJECT MEASURE FREQUENCY   TIME    Value   Flag Codes
0   IRL LTINT   TOT PC_PA   M   1.167610e+18    4.04    NaN
1   IRL LTINT   TOT PC_PA   M   1.170288e+18    4.07    NaN
2   IRL LTINT   TOT PC_PA   M   1.172707e+18    3.97    NaN
3   IRL LTINT   TOT PC_PA   M   1.175386e+18    4.19    NaN
4   IRL LTINT   TOT PC_PA   M   1.177978e+18    4.32    NaN

The format of Time column was YYYY-DD-MM before i used the following

***df['TIME'] = pd.to_datetime(df['TIME'])
df['TIME'] = pd.to_numeric(df['TIME'])
df['TIME'] = df['TIME'].astype(float)***

In order to fit data i used the following code :

***X=df['TIME']
Y=df['Value']
X_train, X_test, Y_train, Y_test = train_test_split(X, Y, test_size=0.4, random_state=101)
lm= LinearRegression()***

when executing the fit function lm.fit(X_train, Y_train), I got the following error :

        ***ValueError                                Traceback (most recent call last)

Do you have any idea how can i resolve this error ? Thank you in advance.

Change X=df['TIME'] to X=df[['TIME']].

Double brackets gets a dataframe back (2d), single brackets gets a series back (1d)
