with latest das environment installation I cannot open the gui on ubuntu

[stein-e]

after conda update conda, I ran: conda create python=3.8 das -c conda-forge -c ncb -n das. When trying to execute das gui I get:

Traceback (most recent call last):
  File "/home/local/UG-STUDENT/elsa.steinfath/miniconda3/envs/das/bin/das", line 7, in <module>
    from das.cli import main
  File "/home/local/UG-STUDENT/elsa.steinfath/miniconda3/envs/das/lib/python3.8/site-packages/das/cli.py", line 3, in <module>
    from . import train, predict, train_tune
  File "/home/local/UG-STUDENT/elsa.steinfath/miniconda3/envs/das/lib/python3.8/site-packages/das/train_tune.py", line 17, in <module>
    import keras_tuner as kt
ModuleNotFoundError: No module named 'keras_tuner'

with conda list, i see that keras-tuner is installed (version 1.0.1). I ran conda install -c conda-forge keras-tuner (and also tried it with a pip install another time), for das gui I get now:

E tensorflow/stream_executor/cuda/cuda_driver.cc:271] failed call to cuInit: CUDA_ERROR_NO_DEVICE: no CUDA-capable device is detected

These are two independent errors. First part of the bug report should be fixed in the latest release. Opened new issue #20 for the second part.
