IOError [Errno 2] Pickle error in python

Question

I have a file analyze.py where I have :

model = joblib.load('svm-model-1.pkl')

When I run my python server where analyze.py is called, I get the following error:

File "/usr/lib/python2.7/dist-packages/joblib/numpy_pickle.py", line 443, in load
        with open(filename, 'rb') as file_handle:
    IOError: [Errno 2] No such file or directory: '/static/analysis/sleep_apnea_IHR_web_Integration/svm-model-1.pkl'

analyze.py and svm-model-1.pkl are both in the same directory. So, it is not the path issue. Could you tell how to solve this error?

Answer 1

Simplest solution is to use the full path. Either hard code it:

model = joblib.load('/path/to/svm-model-1.pkl')

or construct it:

import os
location = '/the/path'
fullpath = os.path.join(location, 'svm-model-1.pkl')
model = joblib.load(fullpath)

If that fails, as commented by immortal you should check the permissions.

Answer 2

Pickel should help easily:

a=[1,2,3,4]
file=open("file","wb")
import pickle
pickle.dump(a,file)
file.close()
file=open("file","rb")
b=pickle.load(file)
file.close()
print(b)

will print give result as

[1,2,3,4]
