Permission denied when installing Tensorflow

Question

I am trying to install TensorFlow by Anaconda(My Python is 3.5.2 edition).

When I run:

(tensorflow)C:> pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-1.0.1-cp35-cp35m-win_amd64.whl 

According to the guide in Tensorflow.org, the following tips emerge:

Exception:
Traceback (most recent call last):

with open(dst, 'wb') as fdst:
PermissionError: [Errno 13] Permission denied: 'C:\\Users\\Anaconda3\\Lib\\site-packages\\numpy\\core\\multiarray.cp35-win_amd64.pyd'

I don't know what causes this error. Can someone help me with that?

Answer 1

Might be late but I got the exact same error and this is what happened. My issue was that there was some file that was being used inside numpy that was locked by anaconda(or some other process) I guess and tensorflow needed that file. Hence I got permission denied. All I did was shut down every process anaconda, jupyter etc and ran:

1) conda update --all
2) pip install --ignore-installed tensorflow

Open your cmd as an administrator and do not activate tensorflow. Just simply fire commands from your cmd. For eg: C:\\> pip install --ignore-installed tensorflow (your directory may vary) should be fine. Let me know if you get stuck.

Answer 2

Maybe because there are other processes using tensorflow. Try to close these processes and then install or update tensorflow.
