Installation of the version 1.1

[bmi-lsym]

Hello,

I wanted to upgrade to SimBA 1.1 (installation of the previous 1.0 version went smoothly).
Using Anaconda3 command prompt.

Followed the instructions on Github page:

git clone -b master https://github.com/sgoldenlab/simba.git
pip install -r simba/simba/requirements.txt

FFmpeg was already installed.

Then, in Anaconda3 run

python SimBA.py

SimBA GUI did not start, and instead resulted in the error message listed below.

Tried to go around by cloning the Tensorflow-free installation, repeating all the steps above and the following command:

git clone -b SimBA_no_TF https://github.com/sgoldenlab/simba.git

As a result, got the same error message.

Tried uninstalling Anaconda, then installed Anaconda & DeepLabCut newly, then repeated SimBA installation steps.... unfortunately, the same outcome.

Could you please help?

Thank you very much in advance.

Sincerely,
Olexiy.

Ok, after trying a bit more myself, following the error message, could fix the issue by manually copying the missing file "geos_c.dll" from its source location "...\anaconda3\Lib\site-packages\shapely\DLLs" to the required location "...\anaconda3\Library\bin".

Thank for for posting the error and the fix! We have added this to our notes to look into further. Please let us know if anything else pops up

i encountered the same problem but was able to solve it using
conda install shapely
a quick google suggests that using pip does not install the correct versions for windows users.
Note: i just installed shapely on top of you requirements.txt, it worked.
