Installation for using TPOT-cuML configuration

I am getting this error while installing TPOT-cuML on a Debian 11
```
/anaconda3/lib/python3.9/site-packages/conda_env/env.py", line 37, in validate_keys
new_data = data.copy() if data else {}
AttributeError: 'str' object has no attribute 'copy'
```

The command line is:
```
conda-env create -n tpot-cuml --file /home/Downloads/tpot-cuml.yml
```
I have also tried this one:
```
conda env create -n tpot-cuml --file /home/Downloads/tpot-cuml.yml
```
But it returns the same error.

The detailed info:
```

```
The spaces after semicolons also were deleted in the tpot-cuml.yml file. Kinda like this:
```
{"groups": [],
...
{"groups":[],
```

To reproduce the issue user needs to install TPOT-cuML using downloaded yaml file.

Expected result: TPOT-cuML installed

Current result: TPOT-cuML installation fails
