AttributeError: module 'mrcfile' has no attribute 'open

[kimdn]

I installed mrcfile by pip.

import mrcfile
went through well.

However,
with mrcfile.open('EMD-3197.map') as mrc:
resulted in

"AttributeError: module 'mrcfile' has no attribute 'open"

print (mrcfile.validate('EMD-3197.map'))
resulted in
AttributeError: module 'mrcfile' has no attribute 'validate'
as well.

/Users/kimd999/Library/Python/2.7/bin
that has
f2py, mrcfile-header, mrcfile-validate are in my PATH.

Can I know why I can't run mrcfile?
I can't run mrcfile both in my macOS (10.14.6) and Linux (centos).

Installation by
conda install --channel conda-forge mrcfile
also didn't help the situation.

I haven't seen this error before so I'm not quite sure what the problem is here! Could you please run the following commands in python and show me the output? import mrcfile print dir(mrcfile) print mrcfile.__file__ Also, on the command line, please try: mrcfile-validate EMD-3197.map

Sorry for my embarrassing question,

it looks like when I specified
import mrcfile
it tried to read my local mrcfile.py instead.

That's why it can't find open and validate attributes.

When I changed mrcfile.py to test.py and ran again, no error happened.

Now,

import mrcfile
print dir(mrcfile)
print mrcfile.__file__

results in

['builtins', 'doc', 'file', 'name', 'package', 'path', 'version', 'absolute_import', 'bzip2mrcfile', 'constants', 'division', 'dtypes', 'future_mrcfile', 'gzipmrcfile', 'load_functions', 'mmap', 'mrcfile', 'mrcinterpreter', 'mrcmemmap', 'mrcobject', 'new', 'new_mmap', 'open', 'open_async', 'print_function', 'unicode_literals', 'utils', 'validate', 'validator', 'version']
/Users/kimd999/Library/Python/2.7/lib/python/site-packages/mrcfile/init.pyc

Also
command line of

mrcfile-validate EMD-3197.map

results in

File does not declare MRC format version 20140: nversion = 0

when EMD-3197.map came from

https://github.com/ccpem/mrcfile/blob/master/tests/test_data/EMD-3197.map

or from
