I followed the instructions here

Steps 1 and 2 have been checked. My Intel(R) Core(TM) i7-2860QM CPU @ 2.50GHz CPU can support 64-bit and Intel virtalization tech and it is currently using virtualization tech according to my BIOS. Checking step 3: I'm on Ubuntu so no antivirus software and I'm not running any system level debugging. Now see the attached image, even though I set the VM to be 64-bit on the left, it is still 32-bit on the right.

enter image description here

I know that the settings are merely for organizational purposes and that they can't actually change the bitness of the VM. I downloaded the VM here - https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/linux/. None of them are marked as 64-bit, so I do not know how to guarantee that I have a 64-bit Windows image

This is not the main issue I'm trying to solve though. It has been inferred as being the cause of my main issue.


Same code works on Ubuntu 14.04 but not the Windows 7 VM. Below you'll see me debugging and all variables look identical.

Next I type the error-causing line into the console and sure enough on one OS we have no issues and on the other we blow up

enter image description here

>>> np.asarray(frames, dtype=np.float32)
    Traceback (most recent call last):
      File "C:\Program Files\JetBrains\PyCharm 2016.1.2\helpers\pydev\_pydevd_bundle\pydevd_exec.py", line 3, in Exec
        exec exp in global_vars, local_vars
      File "<input>", line 1, in <module>
      File "C:\Python27\lib\site-packages\numpy\core\numeric.py", line 482, in asarray
        return array(a, dtype, copy=False, order=order)
    MemoryError

Now the part that gives me the creeps. When I go back to the debugging tab from the console in Ubuntu I see many new variables have spontaneously been created even though I only typed one line into the Python console

enter image description here

enter image description here

I figure there should be a package problem.

I'm using Python 2.7.11 on the Windows 7 VM and these packages are installed

You've got MemoryError. Means you requested allocation which is beyond available memory on your VM. Some potential reasons:

  • not enough memory allocated for VM (try to increase it)
  • 2GB limit for process on Windows (run LARGEADDRESSAWARE python or move to 64 bit)
  • memory corruption so your heap is corrupted (debug your code)

  • To suggestions 1+2: I want to but keep being capped at 4GB since the VM is 32-bit, so I want a 64-bit VM. Today is my first day using VMs so forgive my ignorance but where are all the 64-bit VMs that work with VirtualBox? None of these 'official' ones seem to be 64-bit. https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/linux/ To your suggestion 3: Can you please elaborate more on how memory corruption can occur such that for identical code, it doesn't occur when the code is run on Ubuntu but does occur on Windows? Thank you – Frikster May 11 '16 at 04:40
  • @DirkHaupt I typically download 64-bit Linux VMs from http://www.osboxes.org/, I don't know where to get 64-bit Windows VMs, myself I'm running windows host and linux VMs. – Severin Pappadeux May 11 '16 at 15:00
  • @DirkHaupt concerning 3, systems have quite different ways to do heap allocation. If you corrupt heap on one system, it might go unnoticed on another. But I would concentrate on trying to get to 64bit python first – Severin Pappadeux May 11 '16 at 15:13
  • Okay, so I gave up on trying to find a 64bit VM. I set everything up on a 64bit machine and It is working now without error... If someone can please add where we can find 64bit Windows VM's that would still be really helpful, thanx. – Frikster May 13 '16 at 04:30
