[python] Unable to allocate array with shape and data type

I had this same problem on Window's and came across this solution. So if someone comes across this problem in Windows the solution for me was to increase the pagefile size, as it was a Memory overcommitment problem for me too.

Windows 8

1. On the Keyboard Press the WindowsKey + X then click System in the popup menu
2. Tap or click Advanced system settings. You might be asked for an admin password or to confirm your choice
3. On the Advanced tab, under Performance, tap or click Settings.
4. Tap or click the Advanced tab, and then, under Virtual memory, tap or click Change
5. Clear the Automatically manage paging file size for all drives check box.
6. Under Drive [Volume Label], tap or click the drive that contains the paging file you want to change
7. Tap or click Custom size, enter a new size in megabytes in the initial size (MB) or Maximum size (MB) box, tap or click Set, and then tap or click OK
8. Reboot your system

Windows 10

1. Press the Windows key
2. Type SystemPropertiesAdvanced
3. Click Run as administrator
4. Under Performance, click Settings
5. Select the Advanced tab
6. Select Change...
7. Uncheck Automatically managing paging file size for all drives
8. Then select Custom size and fill in the appropriate size
9. Press Set then press OK then exit from the Virtual Memory, Performance Options, and System Properties Dialog
10. Reboot your system

Note: I did not have the enough memory on my system for the ~282GB in this example but for my particular case this worked.

EDIT

From here the suggested recommendations for page file size:

There is a formula for calculating the correct pagefile size. Initial size is one and a half (1.5) x the amount of total system memory. Maximum size is three (3) x the initial size. So let's say you have 4 GB (1 GB = 1,024 MB x 4 = 4,096 MB) of memory. The initial size would be 1.5 x 4,096 = 6,144 MB and the maximum size would be 3 x 6,144 = 18,432 MB.

Some things to keep in mind from here:

However, this does not take into consideration other important factors and system settings that may be unique to your computer. Again, let Windows choose what to use instead of relying on some arbitrary formula that worked on a different computer.

Also:

Increasing page file size may help prevent instabilities and crashing in Windows. However, a hard drive read/write times are much slower than what they would be if the data were in your computer memory. Having a larger page file is going to add extra work for your hard drive, causing everything else to run slower. Page file size should only be increased when encountering out-of-memory errors, and only as a temporary fix. A better solution is to adding more memory to the computer.
