ValueError: The truth value of an array with more than one element is ambigious

Hi! I meet another problem: Traceback (most recent call last): File "/cvmfs/mlgpu.ihep.ac.cn/anaconda3/envs/tensorflow-gpu/lib/python3.6/runpy.py", line 193, in _run_module_as_main "main", mod_spec) File "/cvmfs/mlgpu.ihep.ac.cn/anaconda3/envs/tensorflow-gpu/lib/python3.6/runpy.py", line 85, in _run_code exec(code, run_globals) File "/hpcfs/bes/mlgpu/cuijb/CaloGAN/models/train.py", line 232, in sparsity_mbd=True File "/hpcfs/bes/mlgpu/cuijb/CaloGAN/models/architectures.py", line 111, in build_discriminator empirical_sparsity = sparsity_detector(image) File "/cvmfs/mlgpu.ihep.ac.cn/anaconda3/envs/tensorflow-gpu/lib/python3.6/site-packages/keras/engine/topology.py", line 596, in call output = self.call(inputs, **kwargs) File "/cvmfs/mlgpu.ihep.ac.cn/anaconda3/envs/tensorflow-gpu/lib/python3.6/site-packages/keras/layers/core.py", line 652, in call return self.function(inputs, **arguments) File "/hpcfs/bes/mlgpu/cuijb/CaloGAN/models/ops.py", line 105, in sparsity_level K.cast(x > 0.0, K.floatx()), axis=np.arange(1, len(_shape)) File "/cvmfs/mlgpu.ihep.ac.cn/anaconda3/envs/tensorflow-gpu/lib/python3.6/site-packages/keras/backend/tensorflow_backend.py", line 1189, in sum axis = _normalize_axis(axis, ndim(x)) File "/cvmfs/mlgpu.ihep.ac.cn/anaconda3/envs/tensorflow-gpu/lib/python3.6/site-packages/keras/backend/tensorflow_backend.py", line 1134, in _normalize_axis if axis is not None and axis < 0: ValueError: The truth value of an array with more than one element is ambiguous.
