numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject
问题背景：
I want to call my Python module from the Matlab. I received the error:
Error using numpy_ops>init thinc.backends.numpy_ops Python Error:
ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject.The Python script is as follows
import spacy def text_recognizer(model_path, text): try: # Load the trained model nlp = spacy.load(model_path) print("Model loaded successfully.") # Process the given text doc = nlp(text) ent_labels = [(ent.text, ent.label_) for ent in doc.ents] return ent_labelsThe Matlab script is as follows
% Set up the Python environment pe = pyenv; py.importlib.import_module('final_output'); % Add the directory containing the Python script to the Python path path_add = fileparts(which('final_output.py')); if count(py.sys.path, path_add) == 0 insert(py.sys.path, int64(0), path_add); end % Define model path and text to process model_path = 'D:\trained_model\\output\\model-best'; text = 'Roses are red'; % Call the Python function pyOut = py.final_output.text_recognizer(model_path, text); % Convert the output to a MATLAB cell array entity_labels = cell(pyOut); disp(entity_labels);I found one solution to update Numpy, what I did, but nothing changed. I am using Python 3.9 and Numpy version 2.0.0
The error was received when I tried to call the Python module using a Matlab script.
How can I fix the issue?
问题解决：
The reason is that pandas defines its numpy dependency freely as "anything newer than certain version of numpy". The problem occured, when numpy==2.0.0 has been released on June 16th 2024, because it is no longer compatible with your pandas version.
The solution is to pin down the numpy version to any before the 2.0.0. Today it could be (this is the most recent numpy 1 release):
numpy==1.26.4 To be added in your requirements or to the pip command you use (but together with installing pandas).
Nowadays pip is very flexible and can handle the issue flawesly. You just need to ask it to install both pandas and numpy of given versions in the same pip install invocation.
