Memory Allocating Error

[Tariq Naveed]

Greetings, I am facing a memory allocation error while estimating the hybrid choice model. Could you please advise me on how to resolve this issue?

  

XlaRuntimeError: INTERNAL: Buffer Definition Event: Error dispatching computation: Error dispatching computation: Error dispatching computation: Error dispatching computation: Error dispatching computation: Error preparing computation: Out of memory allocating 1283840000 bytes. when I use 1000 draws, a memory error occurs. I have 1 TB of SSD disk space and 32 GB of RAM.   

Thanks

Best regards

Use the latest version of Biogeme, that has just been released.
Also, do not run your script in a jupyter notebook. Run it directly from a shell, a terminal.
For large datasets and large number of draws, prefer linux or mac over windows.
