I would check the OS log first, then do "ulimit -a". If there are sar or vmstat on the system, I would definitely use them. Running out of memory is an OS error and should be checked on the OS level. -- Mladen Gogala Database Consultant http://mgogala.byethost5.com -- https://mail.python.org/mailman/listinfo/python-list

If that's the case then using 64-bit Python might fix it, assuming that it's a 64-bit machine. Yes, it is 64. Excuse me, can you explain how I can fix it? Are you using a 32-bit version of Python or a 64-bit version of Python? If you're not sure, try this from Python: >>> import sys >>> sys.maxsize.bit_length() I get 63 because I'm running a 64-bit version of Python 3. On Windows you can install multiple versions of Python side-by-side. I don't know the procedure for Linux or MacOS. If you're currently using 32-bit Python, you can install the 64-bit version in a folder next to the folder of the 32-bit version (I have C:\Python39 and C:\Python39-32, for example). Then install any other packages you need for the new version. -- https://mail.python.org/mailman/listinfo/python-list

What is "64" - the machine or the Python package? >From where did you download Python? What is the code being used to read/load the image? What do you mean by "the sentinel-2 image" - most of the images (which I spotted in a *quick* survey) made available to the general public are of the order of tens of mega-bytes.

open sentinel-2image python
Dear all , When I open the sentinel-2 image in Python, I get the following error: MemoryError: Unable to allocate 115. MiB for an array with shape (5490, 5490) and data type float32 How can I fix it? Thanks -- https://mail.python.org/mailman/listinfo/python-list
