MemoryError at get_data (memory is available according to Task Manager)

[Dennis182]

Hi, thanks for providing the data.
Does the following error affect several users or does it only occur with me? Even if I change the function call as recommended, I get the MemoryError.
.../kits19/starter_code/visualize.py:81: DeprecationWarning: get_data() is deprecated in favor of get_fdata(), which has a more predictable return type. To obtain get_data() behavior going forward, use numpy.asanyarray(img.dataobj).

• deprecated from version: 3.0
• Will raise <class 'nibabel.deprecator.ExpiredDeprecationError'> as of version: 5.0

Interesting... this is the first I've heard of an issue like this. Some of the files are rather large. How much RAM does your system have?

Hello, I also met this problem, how do you solve it?

[ELKYang]

I have solved it
Change the python interpreter to anaconda
