Summary: make sure the text file exists or you used the correct path to the file;
Code to reproduce the error:
from numpy.ma.mrecords import fromtextfile
import tempfile
import os
random_content = ("""
'One (S)','Two (I)','Three (F)','Four (M)','Five (-)','Six (C)'
'strings',1,1.0,'mixed column',,1
""")
with tempfile.TemporaryDirectory() as tmpdir:
temp_file = os.path.join(tmpdir,"file.txt")
with open(temp_file, 'w') as f:
f.write(random_content)
my_text_file = "wrong_file_path.txt" # none existng file path(incorrect file path)
mrectxt = fromtextfile(my_text_file, delimitor=',')
print("content from file\n\n",mrectxt)
Fixed version of the code:
from numpy.ma.mrecords import fromtextfile
import tempfile
import os
random_content = ("""
'One (S)','Two (I)','Three (F)','Four (M)','Five (-)','Six (C)'
'strings',1,1.0,'mixed column',,1
""")
with tempfile.TemporaryDirectory() as tmpdir:
temp_file = os.path.join(tmpdir,"file.txt")
with open(temp_file, 'w') as f:
f.write(random_content)
my_text_file = temp_file #Here we are using the correct file path created above
mrectxt = fromtextfile(my_text_file, delimitor=',')
print("content from file\n\n",mrectxt)
