Error while installing requirements.txt

[harishkhollam999]

Previously it was working but I guess due to some package dependency the error started coming up.
following is the stack trace

In case anyone still has this problem, I got it running like as follows:

0. Change requirements.txt to add explicit tf version (1.12.x -> 1.12.3)

Keras==2.2.*
Pillow==5.3.*
tensorflow-serving-api==1.12.3

1. Install old python version 3.6:

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.6

2. Start virtual env with 3.6:

virtualenv --python=python3.6 myvenv
source myvenv/bin/activate

3. Manually install old tensorflow version 1.12.3 (assuming linux x86_64):

export TF_BINARY_URL=https://files.pythonhosted.org/packages/cc/7b/5bdce6b6323b314ce44aa5be7b531ba0e70c50ecd18e91bd1823ff9b539d/tensorflow-1.12.3-cp36-cp36m-manylinux1_x86_64.whl
pip install --ignore-installed --upgrade $TF_BINARY_URL

4. continue as documented:

pip install -r contrib/tf_serving/requirements.txt
