Pandas : Key error while slicing Pandas Dataframe












3















I am trying to split the Pandas Dataframe into Train and Test.



Example:



Y = final_dataset['Species']
X = final_dataset[X_best_features]

X_train = X[0:120]
X_test = X[120:150]

y_train = Y[0:120]
y_test = Y[120:150]


Now I am using Hyperopt to get the best classifier.



estimator = hpsklearn.HyperoptEstimator(
preprocessing=hpsklearn.components.any_preprocessing('pp'),
classifier=hpsklearn.components.any_classifier('clf'),
algo=hyperopt.tpe.suggest,
trial_timeout=15.0, # seconds
max_evals=15,
)

fit_iterator = estimator.fit_iter(X_train,y_train)
fit_iterator.__next__()
plot_helper = hpsklearn.demo_support.PlotHelper(estimator,
mintodate_ylim=(-.01, .05))
while len(estimator.trials.trials) < estimator.max_evals:
fit_iterator.send(1) # -- try one more model
plot_helper.post_iter()
plot_helper.post_loop()

# -- Model selection was done on a subset of the training data.
# -- Now that we've picked a model, train on all training data.
estimator.retrain_best_model_on_full_data(X_train, y_train)

print('Best preprocessing pipeline:')
print('')
for pp in estimator._best_preprocs:
print(pp)
print('')
print('Best classifier:n', estimator._best_learner)
test_predictions = estimator.predict(X_test)
acc_in_percent = 100 * np.mean(test_predictions == y_test)
print('')
print('Prediction accuracy in generalisation is %.1f%%' % acc_in_percent)


After running the above code I am getting this error:



KeyError: '[ 0  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24n 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49n 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74n 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95] not in index'


Can anyone help me with this error??



Thanks

  • Your data set doesn't have the indices mentioned in the error. So it's raising an error when you try to access them.

  • Can you provide the line number on which the error is raised?

I have solved the above problem by converting X and Y into Numpy array.
It seems that Hyperopt only takes numpy array as input and not Pandas Dataframe.
