Errors when running demo_confidence_map.py with solver_mode='gpu'

[LeeKeyu]

Hi,

Thank you for sharing the code. I tried to run your python script "demo_confidence_map.py", and it worked well when mode=='bf' and 'cg'. However, when I turn the mode to be 'gpu', it throws this error:
File "/home/likeyu/lab/UltrasondConfienceMap/python/confidence_map.py", line 387, in confidence_map
X = np.array([_clean_labels_ar(Xline, labels, copy=True).reshape(dims) for Xline in X])
File "/home/likeyu/lab/UltrasondConfienceMap/python/confidence_map.py", line 387, in
X = np.array([_clean_labels_ar(Xline, labels, copy=True).reshape(dims) for Xline in X])
File "/home/likeyu/lab/UltrasondConfienceMap/python/confidence_map.py", line 127, in _clean_labels_ar
X = X.astype(labels.dtype)
AttributeError: 'Vector' object has no attribute 'astype'

When I change the line "X = X.astype(labels.dtype)" in the function _clean_labels_ar to be
"X = np.array(X, dtype=labels.dtype)", it throws another error:
......
File "/home/likeyu/lab/UltrasondConfienceMap/python/confidence_map.py", line 128, in _clean_labels_ar
X = np.array(X, dtype=labels.dtype)
ValueError: setting an array element with a sequence.

I have not figured out what caused the problem. May I ask for your help? Thank you very much in advance!

Best regards,
Keyu

@LeeKeyu Could you solve this issue? I am having the similar issues with GPU mode
