TypeError: can't assign a numpy.int64 to a torch.FloatTensor #452

goodproj13 · 2019-02-28T17:34:42Z

Guys,
Did anyone know what caused this issue below? Many thanks in advance.
Torch: 0.40
Python: 3.6

We use voc format of KITTI dataset. The only thing I changed for the original code from this repo is to change the picture format from "jpg" to "png" which is the format for KITTI dataset. When I run ''python trainvel_net.py", I got error below:

Traceback (most recent call last):
File "trainval_net.py", line 209, in
imdb.num_classes, training=True)
File "/home/NewPartion/pycharm/faster-rcnn.pytorch/lib/roi_data_layer/roibatchLoader.py", line 54, in init
self.ratio_list_batch[left_idx:(right_idx+1)] = target_ratio
TypeError: can't assign a numpy.int64 to a torch.FloatTensor

please paste all the output from your training run.. so we can see if you enabled CUDA, etc...

ma-xu · 2019-04-12T15:26:28Z

Did you solve this problem? I have the same issue ...

goodproj13 · 2019-04-12T15:28:50Z

I didn't solve the problem and I ended up using other's. Sorry!

Maybe I should try mmdetection or Detectron ...

Weizhongjin · 2019-04-16T07:07:51Z

Change original code to
temp = torch.ones(batch_size)*target_ratio
self.ratio_list_batch[left_idx:(right_idx+1)] = temp

benedictflorance · 2019-06-04T16:05:09Z

@Weizhongjin

Change original code to
temp = torch.ones(batch_size)*target_ratio
self.ratio_list_batch[left_idx:(right_idx+1)] = temp

Doing the above fix throws this error:

**TypeError: mul() received an invalid combination of arguments - got (numpy.int64), but expected one of:
 * (Tensor other)
      didn't match because some of the arguments have invalid types: (numpy.int64)
 * (float other)
      didn't match because some of the arguments have invalid types: (numpy.int64)

**

Has anyone found a fix for this?

Can you possibly upgrade to PyTorch 1.0 ? I've used exclusively 1.x and had zero issues for months now

benedictflorance · 2019-06-04T16:37:54Z

@EMCP I'm working on domain adaptation (https://github.com/tiancity-NJU/da-faster-rcnn-PyTorch) and it uses the PyTorch 0.4 version of this repo. :(

EMCP · 2019-06-04T16:40:49Z

okay i am abroad from my deep learning rig, so I cannot test PyTorch .4 until mid June... but I would diff the two versions and ensure you've got any/all bug fixes pushed to the 1.x version... I never ran the Master branch so I cannot get a sense if it's been properly patched or not..

IMO , the repo owner should just do a release branch for older PyTorch versions and stick to the bleeding edge in Master root, instead of this 1.x off on the side strategy.

benedictflorance · 2019-06-06T17:07:32Z

self.ratio_list_batch[left_idx:(right_idx+1)] = torch.tensor(target_ratio.astype(np.float64)) # trainset ratio list ,each batch is same number
This fixed the issue for 0.4.0

viniciusarruda · 2020-02-13T13:05:40Z

Solving this definitely, in this line, change:

ratio_large = 2 # largest ratio to preserve.

to:

ratio_large = 2.0 # largest ratio to preserve.

PyTorch is creating a tensor with these values and its type is inferred from the data. A value of 2 will be inferred as int, thus, changing to a floating point value will fix it.
Note that this error only occurs when it falls in this if statement. The below if statement uses ratio = ratio_small where ratio_small = 0.5 is already a floating point value as defined in the beginning of the function.
