Error while look to the first emplacement of a scalar numpy array

[PoissonChasseur]

Description

What steps will reproduce the problem?

(Step #1 to #3 can be skip)

1. With PyTorch, calculate the mean of tensor of 60000x28x28 in float64 with value between [0,1]
2. Save this result in a variable "a"
3. b = a.numpy() to get the variable in a array of size [1] with the value.
4. Try to do: a.numpy()[0] or b[0]

Note in fact, this issue could probably just be closed. The Spyder "Issue report" just open when I got this error.

Could you provide an example that doesn't involve steps 1. to 3. but does generate the same error? Thanks!

[PoissonChasseur]

In fact, I can have the message of error with any Numpy array of only 1 value that will be like

Traceback (most recent call last):

  File "<ipython-input-90-6a1284577a36>", line 1, in <module>
    a[0]

IndexError: too many indices for array

But when I had the error when I opened this problem, even Anaconda said that there was something broken and that I could not install another library after (I tried with " conda install pyopengl "to repair Spyder). I just uninstall Spyder and reinstall it to be sure.

I was not really able after to reproduce the same pattern after.

Ok, thanks for letting us know about it. Closing then.
