Anyone tried the test code?

1

Hi there,

I was trying to test if my pytorch is installed correctly on a CentOS-based server. I found there are a set of programs under test dir could do the job. But when I try to run run_test.sh, it always gives me the error message like:

Traceback (most recent call last):
File “test_torch.py”, line 1896, in test_index
self.assertEqual(reference[2, None], reference[2].unsqueeze(0))
TypeError: indexing a tensor with an object of type NoneType. The only supported types are integers, slices, numpy scalars and torch.ByteTensor.

Anyone know what is going on here? I also tried on my mac, and everything works fine.

Thanks!

what is the version of python on the machine, and how did you install pytorch (wheel or conda)?

3

I use python 2.7 for both mac and centos. They are all installed with conda.

4

could you get more specific than python 2.7? (what is the subversion).
What is the output of the command:
python --version

Also, if it is installed with conda, then I’m surprised that this failure occurs.
What is your conda version?
Also the output of conda list

Here is the output of python and conda version.
Python 2.7.13 :: Anaconda custom (64-bit)
conda 4.3.13

The output of conda list is:

ohhh, i think i know what’s happening.

You installed pytorch from conda, which installs version 0.1.9, but you are running the tests in master, which assume the master branch of torch.
To run the tests for 0.1.9, you can do:

git clone https://github.com/pytorch/pytorch
cd pytorch
git checkout v0.1.9
cd test
./run_test.sh

Thanks for your help! Now the error is gone.

Hi @smth

I ran run_test.sh, got the following error:

ERROR: test_serialization_map_location (__main__.TestTorch)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "test_torch.py", line 2713, in test_serialization_map_location
    tensor = torch.load(test_file_path, map_location=map_location)

AttributeError: Can't get attribute '_rebuild_tensor' on <module 'torch._utils' from '/Users/Natsume/miniconda2/envs/dlnd-tf-lab/lib/python3.5/site-packages/torch/_utils.py'>

In my mac, I ran conda list pytorch , return the following:

pytorch                   0.1.10                   py35_1    soumith

In my downloaded pytorch-master folder, I checked the version inside setup.py and found version = '0.1.10'

How should I solve this error? Thanks!

you are trying to install pytorch via binaries, but run tests for master. See my comment above.

@smth Thanks for your reply!

The error is gone with the following method:

  1. git clone
  2. create a new env
  3. conda install numpy setuptools cmake cffi
  4. pip install -r requirements.txt
  5. python setup.py install

then
6. cd test
7../run_test.sh

I don’t why but there is no error this time.

Thanks

What if I installed PyTorch using Anaconda (Anaconda Navigator), how can I test the installation?
