Error when training: ValueError: setting an array element with a sequence.

[kantajitshaw]

I was running test-object-detector in bin.
It gives me following error:

Training a Linear SVM Classifier
Traceback (most recent call last):
File "../object-detector/train-classifier.py", line 48, in
clf.fit(list(np.array(fds)), labels)
File "/usr/local/lib/python2.7/dist-packages/sklearn/svm/base.py", line 151, in fit
X, y = check_X_y(X, y, dtype=np.float64, order='C', accept_sparse='csr')
File "/usr/local/lib/python2.7/dist-packages/sklearn/utils/validation.py", line 521, in check_X_y
ensure_min_features, warn_on_dtype, estimator)
File "/usr/local/lib/python2.7/dist-packages/sklearn/utils/validation.py", line 382, in check_array
array = np.array(array, dtype=dtype, order=order, copy=copy)
ValueError: setting an array element with a sequence.

Please fix this issue.

Hi,
hog function returns 2 values, so you have to change the line 45 and 55 of extract-features.py with this line
fd,hogimage = hog(im, orientations, pixels_per_cell, cells_per_block, visualize, normalize)

@kantajit did your code work with this solution ?

[akane999]

Yes, that worked.

@akane999 I did the same thing as you said corresponding to the same issue. But I got the error shown as below:
Traceback (most recent call last):
File "../object-detector/extract-features.py", line 58, in
fd,hogimage = hog(im, orientations, pixels_per_cell, cells_per_block, visualize, normalize)
ValueError: too many values to unpack

If I change back, it game me the previous error again. Any advise? thanks

[akane999]

Please check the dimensions of your data, this error means that an argument that should be a single value is an array, so It will not work. So check the dimensions.
