AxisError: axis -1 is out of bounds

I already referred the posts here,here and here

Am trying to run a lassoCV model and fit it on my training dataset.

So, I tried the below code (this works)

from numpy import arange
from sklearn.linear_model import LassoCV
from sklearn.model_selection import RepeatedKFold
# define model evaluation method
cv = RepeatedKFold(n_splits=10, n_repeats=5, random_state=1)
# define model
model = LassoCV(alphas=arange(0, 1, 0.01), cv=cv)
# fit model
model.fit(X_train, y_train)
# summarize chosen configuration
print('alpha: %f' % model.alpha_)  # returns 0.78 as best value
y_pred = model.predict(X_test)

However, when I try the below in next cell of jupyter notebook, I get an error

# define model
model_new = LassoCV(alphas=0.78)
# fit model
model_new.fit(X_train,pd.DataFrame(y_train))  # I also tried just X_train and y_train but still doesn't work

AxisError Traceback (most recent call
last) Input In [136], in <cell line: 4>()
2 model_new = LassoCV(alphas=0.78)
3 # fit model
—-> 4 model_new.fit(X_train,pd.DataFrame(y_train))

AxisError: axis -1 is out of bounds for array of dimension 0

My shape of X_train and y_train looks like below
