npy file size limit

[erichnau]

I am sucessfully using cnpy for the conversion of a custom .fld format to .npy, however, i have lately observed issues with very large files. my npy files are written to a maximum size of 6.81GB - then writing stops but the process continues without any errors. the resulting npy is faulty because the array size specified in the header does not match the data.

Hi, you can try to change lines 85 and 133 in the "cnpy.cpp" file to:

shape.push_back(std::stoul(sm[0].str()));

The original implementation uses std::stoi which cannot support shape dimension > 2,147,483,647.
