Question

当我使用

fits_datasweep_gal = fits.open('Macintosh HD/Users/lingxuan/Downloads/datasweep-index-gal.fits')

要在Jupyter笔记本上打开FITS文件，它将返回：

FileNotFoundError                         Traceback (most recent call last)

我该怎么办？

从路径中删除window.pdfMake = require('pdfmake/build/pdfmake.js'); var vfs = require('pdfmake/build/vfs_fonts.js'); window.pdfMake.vfs = vfs.pdfMake.vfs;部分

使用Astropy打开FITS文件会导致FileNotFoundError
