Value changed after loading a saved tensor

Xiaoyu_Liu: <SCODE>A = torch.from_numpy(A_array)
checkEmpty(A) # passed

torch.save(A, 'A_tensor')
A = torch.load('A_tensor')
checkEmpty(A) # failed
<ECODE> Then to find the first ZERO map: <SCODE>for i in range(A.size()[0]):
		for j in range(A.size()[1]):
			if torch.max(A[i][j]) == 0.0:
				print(i, j)
<ECODE>

Xiaoyu_Liu: Thank you. But how to check the version of currently used Pytorch?

smth: What OS are you on? I just tried this small snippet on Linux (CentOS7) and on OSX: <SCODE>import torch

a = torch.ones(800*3*480*640)
print(a.eq(0).sum())
torch.save(a, 'a.pth')
b = torch.load('a.pth')

print(b.eq(0).sum())
<ECODE> On Linux it works fine, on OSX i get an error, which i am investigating: <SCODE>0
Traceback (most recent call last):
  File "a.py", line 5, in <module>
    torch.save(a, 'a.pth')
  File "/Users/soumith/code/pytorch/torch/serialization.py", line 120, in save
    return _save(obj, f, pickle_module, pickle_protocol)
  File "/Users/soumith/code/pytorch/torch/serialization.py", line 192, in _save
    serialized_storages[key]._write_file(f)

Xiaoyu_Liu: Thank you, I’m working on Ubuntu 14.04.1

Xiaoyu_Liu: 

smth: I tried it on an ubuntu 14.04 as well, but couldn’t reproduce the issue. <SCODE>lsb_release -a

Xiaoyu_Liu: But when I try to install the latest version, this error happens, <SCODE>SSLError: [Errno 1] _ssl.c:510: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure
<ECODE> If you are experienced with it, can you tell me how to solve that? If not, I’ll figure out it somewhere else:smiley:

apolis: Hello, do and try installing the package again.

Xiaoyu_Liu: Thanks! But after installing these, the problem can’t be solved yet… Then I refreshed the pytorch website to install again, it works. Magical…
