## Installation problems |
|
|
|
|
|
|
|
### Tensorflow dependency |
|
|
|
ML Agents requires TensorFlow; if you don't already have it installed, `pip` will try to install it when you install |
|
|
|
the ml-agents package. |
|
|
|
|
|
|
|
If you see a message like this |
|
|
|
```console |
|
|
|
ERROR: Could not find a version that satisfies the requirement tensorflow<2.0,>=1.7 (from mlagents) (from versions: none) |
|
|
|
ERROR: No matching distribution found for tensorflow<2.0,>=1.7 (from mlagents) |
|
|
|
``` |
|
|
|
it means that there is no version of TensorFlow for your python environment. Some known potential causes are: |
|
|
|
* You're using 32-bit python instead of 64-bit. See the answer [here](https://stackoverflow.com/a/1405971/224264) |
|
|
|
for how to tell which you have installed. |
|
|
|
* You're using python 3.8. Tensorflow plans to release packages for this as soon as possible; see |
|
|
|
[this issue](https://github.com/tensorflow/tensorflow/issues/33374) for more details. |
|
|
|
* You have the `tensorflow-gpu` package installed. This is equivalent to `tensorflow`, however `pip` doesn't recognize |
|
|
|
this. The best way to resolve this is to update to `tensorflow==1.15.0` which provides GPU support in the same package |
|
|
|
(see the [release notes](https://github.com/tensorflow/tensorflow/issues/33374) for more details.) |
|
|
|
* You're on another architecture (e.g. ARM) which requires vendor provided packages. |
|
|
|
|
|
|
|
In all of these cases, the issue is a pip/python environment setup issue. Please search the tensorflow github issues |
|
|
|
for similar problems and solutions before creating a new issue. |

## Scripting Runtime Environment not setup correctly |
|
|
|
|
|
|
|
If you haven't switched your scripting runtime version from .NET 3.5 to .NET 4.6 |

# Known Issues |
|
|
|
|
|
|
|
## Release 0.10.0 |
|
|
|
* ml-agents 0.10.0 and earlier were incompatible with TensorFlow 1.15.0; the graph could contain |
|
|
|
an operator that `tensorflow_to_barracuda` didn't handle. This was fixed in the 0.11.0 release. |
