Python Error:OSError: [Errno 22] Invalid argument

Question

Traceback (most recent call last):

File "C:\Users\yang6\PycharmProjects\DeepHyperX\models.py", line 1059, in train save_model(net, camel_to_snake(str(net.__class__.__name__)), data_loader.dataset.name, epoch=e, metric=abs(metric))

OSError: [Errno 22] Invalid argument: './checkpoints/hamida_et_al/PaviaU/2020-07-03 10:52:46.094626_epoch2_0.78.pth'

My file path is './checkpoints/hamida_et_al/PaviaU/2020-07-03 10:52:46.094626_epoch2_0.78.pth', so how to settle it?

enter image description here

My Code：

def save_model(model, model_name, dataset_name, **kwargs):
 model_dir = 'C:/Users/yang6/PycharmProjects/DeepHyperX/checkpoints/' + model_name + "/" + dataset_name + "/"
 if not os.path.isdir(model_dir):
     os.makedirs(model_dir, exist_ok=True)
 if isinstance(model, torch.nn.Module):
     filename = str(datetime.datetime.now()) + "_epoch{epoch}_{metric:.2f}".format(**kwargs)
     tqdm.write("Saving neural network weights in {}".format(filename))
     torch.save(model.state_dict(), model_dir + filename + '.pth')
 else:
     filename = str(datetime.datetime.now())
     tqdm.write("Saving model params in {}".format(filename))
     joblib.dump(model, model_dir + filename + '.pkl')

please present your code not only the errors – Tony Jul 03 '20 at 06:42 — Tony, Jul 03 '20 at 06:42
I have updated my code. Could you help me? – Bruce Young Jul 03 '20 at 08:22 — Bruce Young, Jul 03 '20 at 08:22

Since your are on Windows and working with PyCharm, it seems to me you need to pass the absolute path to open() rather than the relative path see here.

Further make sure you use the correct escape sequences if there is a blank space in four path, see here.
