问题
I have had problems here, here and there installing tensorflow 2 over the last year or so. So I am trying miniconda.
I have an amd radeon hd 6670 and an amd radeon hd 6450.
I just downloaded miniconda and made an environment and did a pip install --upgrade tensorflow in an miniconda prompt on windows 8.1 and got tensorflow 2.2.
When I try to import tensorflow I get the stack trace below.
I did download visual studio to get the latest redistributebles (I think).
seems like this occurs near this line: from tensorflow.python.pywrap_tensorflow_internal import *
Edit 1: I used this yaml file for python 3.6 (the other was 3.7), but it produced the same error.
Edit 2: I upgraded to conda 4.8.3 and python 3.7 (in the yaml file) and got the same error. This is the line in pywrap internal that shows the problem:
line 28: _pywrap_tensorflow_internal = swig_import_helper()
In swig helper:
fp, pathname, description = imp.find_module('_pywrap_tensorflow_internal', [dirname(__file__)])
Looks like it's trying to find itself? Anyone have a clue?
Edit 3: This looks like the same problem, but it's dated. This seems to be the same problem that got fixed by using 2015 c++ redistributebles. I do have 2015 x64 and 2015-2019 x86 installed.
Edit 4: Trying 3.5 gets a subprocess error (please see below).
Edit 5: Trying 3.7 with: conda install 'tensorflow==mkl' (and no yaml file) did work (3.6 did not work). Unfortunately it still takes 10 seconds to import tf2!
Searching for: -gpu swig_import_helper "Failed to load the native TensorFlow runtime" results in about 3.6k hits, so this is an ongoing problem.
Edit 5: installing keras breaks with this bug. trying the fix gets: AttributeError: module 'tensorflow' has no attribute 'compat'. so tendorflow does not work anymore.
Does anyone have a repeatable process that is stable? I am trying to work with the code from Deep Learning with Python, Second Edition.
Edit 6: unstalling minconda took about an hour. installing a new anaconda worked fine. using their yaml file gets a nice install. but importing tensorflow gets a dll load error.
Edit 7. trying python 3.8 and using a virtual environment is much faster. i can install tensorflow. but using it gets:
ImportError: Could not find the DLL(s) 'msvcp140_1.dll'. TensorFlow requires that these DLLs be installed in a directory that is named in your %PATH% environmen
t variable.
I do have the redistributables installed and windows/system32 is on the path:

Here and here are a similar problems.
Some have suggested copying the dll's to the python path area.
Seems to have turned in to a warning overnight. Now I get:
