chapter 12: 'torch.dtype' object has no attribute 'type'

[NewEnglandML]

Hi, when I start to train the model using "train.scst.py", this error appeared: 'torch.dtype' object has no attribute 'type', I am running pytorch v1. this is complete log of error thanks:

Current version of samples was tested on torch 0.4.1. Port for 1.0 is in progress.

File "/home/farshid/tensorflow/lib/python3.6/site-packages/ptan/common/utils.py", line 329, in track self.writer.add_scalar(param_name, np.mean(data), iter_index) I modified it to self.writer.add_scalar(param_name, torch.mean(torch.stack(data)), iter_index) according to this post and it works

Thanks puppetect, tried this on a similar problem in Chapter14 running; but got the following error 02_train_a2c.py -n test --cuda

File "02_train_a2c.py", line 83, in tb_tracker.track("episode_steps", steps[0], step_idx) File "C:\My_Installs\Anaconda\envs\python36_clone\lib\site-packages\ptan\common\utils.py", line 330, in track self.writer.add_scalar(param_name, torch.mean(torch.stack(data)), iter_index) TypeError: expected Tensor as element 0 in argument 0, but got float

It appears the follow worked for me in this case

self.writer.add_scalar(param_name, np.mean(data, dtype=np.float), iter_index)
