I have checked the directory exists, and I am using Pathlib
As far as I can tell, I have used the same syntax successfully, but for some lines only the code fails with a file does not exist error:
Just one example of failure
print(data_folder.is_dir()) #when I run, returns True
with (data_folder / "lensingtimedelayswithinimage.npy" ).open(mode="w+b") as lensingtimedelaysfile:
np.save(lensingtimedelaysfile, np.array(tdwithinimage))
and returns the error
FileNotFoundError: [Errno 2] No such file or directory: 'C:\Users\angel_000\Documents\ArchiveofDocuments\2019\New_Time_Delay_Code\Thin_Inclined_Ring\Rmax_200_fracinc_0p5\200\LCDM\zs_3_zl_1_c_299792458_H0_75\beta_0p065_0p065\Softened_ellipsoidal_isothermal\b_1_s_0p1_eps_0p1_rotangle_0_centre_00\1001\im0\lensingtimedelayswithinimage.npy'
another example in the same code
data_folder_main.mkdir(parents=True, exist_ok=True)
try:
if (data_folder_main / "imagepositions.npy").stat().st_size == 0:
raise ValueError('Empty file')
with (data_folder_main / "imagepositions.npy").open(mode="rb") as imagepositionsfile:
theta_all_arraylist = np.load(imagepositionsfile)
except (FileNotFoundError, ValueError) as error:
theta_all_arraylist = lensmodel.theta_all_arraylist(betaarray.astype('float64'))
with (data_folder_main / "imagepositions.npy").open(mode="w+b") as imagepositionsfile: #save the image position of the particles
np.save(imagepositionsfile, theta_all_arraylist) #this runs fine each time
with (data_folder_main / "imagepositionscentre.npy").open(mode="w+b") as imagepositionscentrefile: save the image position of the particles
np.save(imagepositionscentrefile, theta_centresource) #this fails each time with file not found
