attributeerror: 'numpy.ndarray' object has no attribute 'to' pytorch

torch.from_numpy(numpy_array) - for numpy arrays;
torch.as_tensor(list) - for common lists and tuples;
torch.tensor(array) should also work but the above ways will avoid copying the data when possible.

'numpy.ndarray' object has no attribute 'cuda' - PyTorch Forums

Hi Sarra, could you use a translation service, please, as my French is quite bad? :stuck_out_tongue: From Deepl: “or I add ( tensor = torch.from_numpy(array)) ? in the source code please ?” If I understand it correctly, you would like to know, where to add this line of code? Try to add it rig…

AttributeError: 'numpy.ndarray' object has no attribute 'numpy' - vision - PyTorch Forums

adv_ex is already a numpy array, so you can’t call .numpy() again on it (which is a tensor method). Store adv_ex as a tensor or avoid calling numpy on it: adv_ex = perturbed_data.squeeze().detach().cpu() adv_examples.append( (init_pred.item(), final_pred.item(), adv_ex) )

Hi @deepgravity This should not happen. RLlib converts the complete content of the input_dict to torch tensors before computing actions. Can you breakpoint into this function? … or maybe to this line and see what happens there? Cheers!
