Description
Describe the bug
we use cvcuda to resize imgs, but found resize param not support cvcuda.Interp.LANCZOS
Steps/Code to reproduce bug
def clip_img2_tensor(self, imgs):
center_croped_tensor_hwc_list = []
for frame in imgs:
h = frame.height
w = frame.width
ratio = float(256.0) / min(w, h)
w_resize, h_resize = int(w * ratio), int(h * ratio)
frame_tensor_hwc = cvcuda.as_tensor(frame,"HWC")
resized_frame_tensor_hwc = cvcuda.resize(frame_tensor_hwc,(h_resize, w_resize, 3), cvcuda.Interp.LANCZOS)
# center_croped_tensor_hwc = cvcuda.center_crop(resized_frame_tensor_hwc, (224, 224))
center_croped_tensor_hwc_list.append(resized_frame_tensor_hwc)
stack_center_croped_tensor_hwc = cvcuda.stack(center_croped_tensor_hwc_list)
nvcvConvertTensor = cvcuda.convertto(stack_center_croped_tensor_hwc, np.float32, scale=1 / 255)
mean_tensor = nvcv.as_tensor(self.scaleTensor, "NHWC")
std_tensor = nvcv.as_tensor(self.stdTensor, "NHWC")
nvcvNormTensor = cvcuda.normalize(nvcvConvertTensor, mean_tensor, std_tensor, cvcuda.NormalizeFlags.SCALE_IS_STDDEV)
nvcvPreprocessedTensor = cvcuda.reformat(nvcvNormTensor, "NCHW")
torch_preprocessed_tensor = torch.as_tensor(nvcvPreprocessedTensor.cuda(), device="cuda")
return torch_preprocessed_tensor
Err is:
message: RuntimeError: NVCV_ERROR_INVALID_ARGUMENT: Invalid interpolation
Expected behavior
how can i use LANCZOS to resize img?
