Subject: [PATCH] Fix Code Issues to Get Unit Tests Running (#121)

* First pass.

* Action on push

* Install deps.

* ubuntu 20?

* Ok, just mac

* Try commenting out the partially implemented models?

* Let failing tests fail

* Tests failing now only for `sample_description_from_xarray` and code-issues

* Fix location and design matrices

* Remove method init_par from Estimator

* Remove rcond because dask doesn't support?

* check chunk type for dask

* Fix tf + dask compat issue.

* Remove TF1 and TF2 Tests

* Downgrade `sparse`

* Make sure arrays are not immutable

* Remove TF mentions

* Remove TF2

* Remove TF from requirements.txt

* Undo erroneous deletion of dep

* Remove constants.

* Remove constants.

* Fix small tensorflow merges issues.

 # Fast and scalable fitting of over-determined generalized-linear models (GLMs)
 
 batchglm was developed in the context of [diffxpy](https://github.com/theislab/diffxpy) to allow fast model fitting for differential expression analysis for single-cell RNA-seq data. However, one can use batchglm or its concepts in other scenarios where over-determined GLMs are encountered.
+
+```
+pip install -r requirements.txt
+```
+
+To run unit tests:
+
+```
+pip install -e .
+python -m unittest
+```
+
 <!-- 
 # Installation
 1. Install [tensorflow](https://www.tensorflow.org/install/), see below. Please use the pip installation if you are unsure.
