Install Modifies TFLite

[msquigle]

Describe the bug
When tf2onnx is installed using pip, if tflite is installed, every schema file for tflite is modified and sometimes there are even files added.

Urgency
Affects other packages that should be unrelated to tf2onnx as tflite 2 onnx is not supported.

System information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Windows 10
• Tensorflow Version: None
• Python version: 3.8

To Reproduce
Create a new virtual environment
$ virtualenv -p 3.8 test_tf2onnx
$ pip install --no-dependencies tflite
$ pip install --no-dependencies tf2onnx

If you create a git repo or have another way of tracking file changes before the tf2onnx install and after the install you will see something similar to the following:

Expected behavior
The install should not be modifying other site-packages as it leads to issues where TFLite models are no longer able to be read properly.

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context

Yes, can confirm - this is bad. There was a short time where we had this and we fixed it in master since but we have not released master yet. Going to release it today.

[msquigle]

Ok great! I will retry this then tomorrow! Thanks

[guschmue]

thanks for catching this !!!

[guschmue]

We released 1.8.2 that has the fix.
pip install -U tf2onnx
should install it.
The PR for the fix is here: #1273

[TomWildenhain-Microsoft]

Yeah this was my mistake. @msquigle let us know if the fix works for you.

[msquigle]

Can confirm fixed in 1.8.2!
